64aa9925e4 totalPressureFvPatchScalarField, uniformTotalPressureFvPatchScalarField: simplified and rationalized
The modes of operation are set by the dimensions of the pressure field
    to which this boundary condition is applied, the \c psi entry and the value
    of \c gamma:
    \table
        Mode                    | dimensions | psi   | gamma
        incompressible subsonic | p/rho      |       |
        compressible subsonic   | p          | none  |
        compressible transonic  | p          | psi   | 1
        compressible supersonic | p          | psi   | > 1
    \endtable

    For most applications the totalPressure boundary condition now only
    requires p0 to be specified e.g.
    outlet
    {
        type            totalPressure;
        p0              uniform 1e5;
    }

83321bd4f7 functionObjects: renamed faceSource -> surfaceRegion, cellSource -> volRegion
The use of the term 'source' in the context of post-processing is
confusing and does not properly describe the process of region
selection.  The new names 'surfaceRegion' and 'volRegion' better
describe the purpose of the functionObjects which is to provide field
processing functionality limited to a specified region of space, either
a surface or volume.

The keyword 'source' is renamed 'regionType' which better describes the
purpose which is to specify the method by which the surface or volume
region is selected.

The keyword to select the name of the surface or volume region is
renamed from 'sourceName' to 'name' consistent with the other
name-changes above.

e4dc50dcb0 postProcessing: Replaced 'foamCalc' and the 'postCalc' utilities
with the more general and flexible 'postProcess' utility and '-postProcess' solver option

Rationale
---------

Both the 'postProcess' utility and '-postProcess' solver option use the
same extensive set of functionObjects available for data-processing
during the run avoiding the substantial code duplication necessary for
the 'foamCalc' and 'postCalc' utilities and simplifying maintenance.
Additionally consistency is guaranteed between solver data processing
and post-processing.

The functionObjects have been substantially re-written and generalized
to simplify development and encourage contribution.

Configuration
-------------

An extensive set of simple functionObject configuration files are
provided in

OpenFOAM-dev/etc/caseDicts/postProcessing

and more will be added in the future.  These can either be copied into
'<case>/system' directory and included into the 'controlDict.functions'
sub-dictionary or included directly from 'etc/caseDicts/postProcessing'
using the '#includeEtc' directive or the new and more convenient
'#includeFunc' directive which searches the
'<etc>/caseDicts/postProcessing' directories for the selected
functionObject, e.g.

functions
{
    #includeFunc Q
    #includeFunc Lambda2
}

'#includeFunc' first searches the '<case>/system' directory in case
there is a local configuration.

Description of #includeFunc
---------------------------

    Specify a functionObject dictionary file to include, expects the
    functionObject name to follow (without quotes).

    Search for functionObject dictionary file in
    user/group/shipped directories.
    The search scheme allows for version-specific and
    version-independent files using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/\<VERSION\>/caseDicts/postProcessing
      - ~/.OpenFOAM/caseDicts/postProcessing
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/\<VERSION\>/caseDicts/postProcessing
      - $WM_PROJECT_SITE/caseDicts/postProcessing
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/\<VERSION\>/caseDicts/postProcessing
      - $WM_PROJECT_INST_DIR/site/caseDicts/postProcessing
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/caseDicts/postProcessing

    An example of the \c \#includeFunc directive:
    \verbatim
        #includeFunc <funcName>
    \endverbatim

postProcess
-----------

The 'postProcess' utility and '-postProcess' solver option provide the
same set of controls to execute functionObjects after the run either by
reading a specified set of fields to process in the case of
'postProcess' or by reading all fields and models required to start the
run in the case of '-postProcess' for each selected time:

postProcess -help

Usage: postProcess [OPTIONS]
options:
  -case <dir>       specify alternate case directory, default is the cwd
  -constant         include the 'constant/' dir in the times list
  -dict <file>      read control dictionary from specified location
  -field <name>     specify the name of the field to be processed, e.g. U
  -fields <list>    specify a list of fields to be processed, e.g. '(U T p)' -
                    regular expressions not currently supported
  -func <name>      specify the name of the functionObject to execute, e.g. Q
  -funcs <list>     specify the names of the functionObjects to execute, e.g.
                    '(Q div(U))'
  -latestTime       select the latest time
  -newTimes         select the new times
  -noFunctionObjects
                    do not execute functionObjects
  -noZero           exclude the '0/' dir from the times list, has precedence
                    over the -withZero option
  -parallel         run in parallel
  -region <name>    specify alternative mesh region
  -roots <(dir1 .. dirN)>
                    slave root directories for distributed running
  -time <ranges>    comma-separated time ranges - eg, ':10,20,40:70,1000:'
  -srcDoc           display source code in browser
  -doc              display application documentation in browser
  -help             print the usage

 pimpleFoam -postProcess -help

Usage: pimpleFoam [OPTIONS]
options:
  -case <dir>       specify alternate case directory, default is the cwd
  -constant         include the 'constant/' dir in the times list
  -dict <file>      read control dictionary from specified location
  -field <name>     specify the name of the field to be processed, e.g. U
  -fields <list>    specify a list of fields to be processed, e.g. '(U T p)' -
                    regular expressions not currently supported
  -func <name>      specify the name of the functionObject to execute, e.g. Q
  -funcs <list>     specify the names of the functionObjects to execute, e.g.
                    '(Q div(U))'
  -latestTime       select the latest time
  -newTimes         select the new times
  -noFunctionObjects
                    do not execute functionObjects
  -noZero           exclude the '0/' dir from the times list, has precedence
                    over the -withZero option
  -parallel         run in parallel
  -postProcess      Execute functionObjects only
  -region <name>    specify alternative mesh region
  -roots <(dir1 .. dirN)>
                    slave root directories for distributed running
  -time <ranges>    comma-separated time ranges - eg, ':10,20,40:70,1000:'
  -srcDoc           display source code in browser
  -doc              display application documentation in browser
  -help             print the usage

The functionObjects to execute may be specified on the command-line
using the '-func' option for a single functionObject or '-funcs' for a
list, e.g.

postProcess -func Q
postProcess -funcs '(div(U) div(phi))'

In the case of 'Q' the default field to process is 'U' which is
specified in and read from the configuration file but this may be
overridden thus:

postProcess -func 'Q(Ua)'

as is done in the example above to calculate the two forms of the divergence of
the velocity field.  Additional fields which the functionObjects may depend on
can be specified using the '-field' or '-fields' options.

The 'postProcess' utility can only be used to execute functionObjects which
process fields present in the time directories.  However, functionObjects which
depend on fields obtained from models, e.g. properties derived from turbulence
models can be executed using the '-postProcess' of the appropriate solver, e.g.

pisoFoam -postProcess -func PecletNo

or

sonicFoam -postProcess -func MachNo

In this case all required fields will have already been read so the '-field' or
'-fields' options are not be needed.

3eec5854be Standardized the selection of required and optional fields in BCs, fvOptions, functionObjects etc.
In most boundary conditions, fvOptions etc. required and optional fields
to be looked-up from the objectRegistry are selected by setting the
keyword corresponding to the standard field name in the BC etc. to the
appropriate name in the objectRegistry.  Usually a default is provided
with sets the field name to the keyword name, e.g. in the
totalPressureFvPatchScalarField the velocity is selected by setting the
keyword 'U' to the appropriate name which defaults to 'U':

        Property     | Description             | Required    | Default value
        U            | velocity field name     | no          | U
        phi          | flux field name         | no          | phi
        .
        .
        .

However, in some BCs and functionObjects and many fvOptions another
convention is used in which the field name keyword is appended by 'Name'
e.g.

        Property     | Description             | Required    | Default value
        pName        | pressure field name     | no          | p
        UName        | velocity field name     | no          | U

This difference in convention is unnecessary and confusing, hinders code
and dictionary reuse and complicates code maintenance.  In this commit
the appended 'Name' is removed from the field selection keywords
standardizing OpenFOAM on the first convention above.

78d2971b21 functionObjects: rewritten to all be derived from 'functionObject'
- Avoids the need for the 'OutputFilterFunctionObject' wrapper
  - Time-control for execution and writing is now provided by the
    'timeControlFunctionObject' which instantiates the processing
    'functionObject' and controls its operation.
  - Alternative time-control functionObjects can now be written and
    selected at run-time without the need to compile wrapped version of
    EVERY existing functionObject which would have been required in the
    old structure.
  - The separation of 'execute' and 'write' functions is now formalized in the
    'functionObject' base-class and all derived classes implement the
    two functions.
  - Unnecessary implementations of functions with appropriate defaults
    in the 'functionObject' base-class have been removed reducing
    clutter and simplifying implementation of new functionObjects.
  - The 'coded' 'functionObject' has also been updated, simplified and tested.
  - Further simplification is now possible by creating some general
    intermediate classes derived from 'functionObject'.

fc2ce73723 Solvers: Added support for extrapolated pressure boundary conditions
The boundary conditions of HbyA are now constrained by the new "constrainHbyA"
function which applies the velocity boundary values for patches for which the
velocity cannot be modified by assignment and pressure extrapolation is
not specified via the new
"fixedFluxExtrapolatedPressureFvPatchScalarField".

The new function "constrainPressure" sets the pressure gradient
appropriately for "fixedFluxPressureFvPatchScalarField" and
"fixedFluxExtrapolatedPressureFvPatchScalarField" boundary conditions to
ensure the evaluated flux corresponds to the known velocity values at
the boundary.

The "fixedFluxPressureFvPatchScalarField" boundary condition operates
exactly as before, ensuring the correct flux at fixed-flux boundaries by
compensating for the body forces (gravity in particular) with the
pressure gradient.

The new "fixedFluxExtrapolatedPressureFvPatchScalarField" boundary
condition may be used for cases with or without body-forces to set the
pressure gradient to compensate not only for the body-force but also the
extrapolated "HbyA" which provides a second-order boundary condition for
pressure.  This is useful for a range a problems including impinging
flow, extrapolated inlet conditions with body-forces or for highly
viscous flows, pressure-induced separation etc.  To test this boundary
condition at walls in the motorBike tutorial case set

    lowerWall
    {
        type            fixedFluxExtrapolatedPressure;
    }

    motorBikeGroup
    {
        type            fixedFluxExtrapolatedPressure;
    }

Currently the new extrapolated pressure boundary condition is supported
for all incompressible and sub-sonic compressible solvers except those
providing implicit and tensorial porosity support.  The approach will be
extended to cover these solvers and options in the future.

Note: the extrapolated pressure boundary condition is experimental and
requires further testing to assess the range of applicability,
stability, accuracy etc.

f4202d9ee6 sixDoFSolver: Run-time selectable solver (integrator) for sixDoFRigidBodyMotion
The built-in explicit symplectic integrator has been replaced by a
general framework supporting run-time selectable integrators.  Currently
the explicit symplectic, implicit Crank-Nicolson and implicit Newmark
methods are provided, all of which are 2nd-order in time:

Symplectic 2nd-order explicit time-integrator for 6DoF solid-body motion:

    Reference:
        Dullweber, A., Leimkuhler, B., & McLachlan, R. (1997).
        Symplectic splitting methods for rigid body molecular dynamics.
        The Journal of chemical physics, 107(15), 5840-5851.

    Can only be used for explicit integration of the motion of the body,
    i.e. may only be called once per time-step, no outer-correctors may be
    applied.  For implicit integration with outer-correctors choose either
    CrankNicolson or Newmark schemes.

    Example specification in dynamicMeshDict:
    solver
    {
        type    symplectic;
    }

Newmark 2nd-order time-integrator for 6DoF solid-body motion:

    Reference:
        Newmark, N. M. (1959).
        A method of computation for structural dynamics.
        Journal of the Engineering Mechanics Division, 85(3), 67-94.

    Example specification in dynamicMeshDict:
    solver
    {
        type    Newmark;
        gamma   0.5;    // Velocity integration coefficient
        beta    0.25;   // Position integration coefficient
    }

Crank-Nicolson 2nd-order time-integrator for 6DoF solid-body motion:

    The off-centering coefficients for acceleration (velocity integration) and
    velocity (position/orientation integration) may be specified but default
    values of 0.5 for each are used if they are not specified.  With the default
    off-centering this scheme is equivalent to the Newmark scheme with default
    coefficients.

    Example specification in dynamicMeshDict:
    solver
    {
        type    CrankNicolson;
        aoc     0.5;    // Acceleration off-centering coefficient
        voc     0.5;    // Velocity off-centering coefficient
    }

Both the Newmark and Crank-Nicolson are proving more robust and reliable
than the symplectic method for solving complex coupled problems and the
tutorial cases have been updated to utilize this.

In this new framework it would be straight forward to add other methods
should the need arise.

0e7de1b8df tutorials/incompressible/simpleFoam/pitzDaily: Change to use SIMPLEC
With the SIMPLE "consistent" option and optimized relaxation factors
this tutorial now converges in 210 iterations, previously with SIMPLE it
took 950.  Despite the increase in cost per time-step due to the
increase in relaxation factors and number of solver iterations the
speed-up is 3.5x.

3a004fda10 fvOptions: Separate options for all cells, cellSets and inter-region coupling
by introducing rational base-classes rather than using the hideous
'switch' statement.  Further rationalization of the cell-selection
mechanism will be implemented via an appropriate class hierarchy to
replace the remaining 'switch' statement.

Mesh-motion is currently handled very inefficiently for cellSets and not
at all for inter-region coupling.  The former will be improved when the
cell-selection classes are written and the latter by making the
meshToMesh class a MeshObject after it has been corrected for mapFields.

c3ee2348a6 MRF: Separate MRF from fvOptions
fvOptions does not have the appropriate structure to support MRF as it
is based on option selection by user-specified fields whereas MRF MUST
be applied to all velocity fields in the particular solver.  A
consequence of the particular design choices in fvOptions made it
difficult to support MRF for multiphase and it is easier to support
frame-related and field related options separately.

Currently the MRF functionality provided supports only rotations but
the structure will be generalized to support other frame motions
including linear acceleration, SRF rotation and 6DoF which will be
run-time selectable.

38177526ff simpleFoam/SRFSimpleFoam: Added support for SIMPLEC
SIMPLEC (SIMPLE-consistent) is selected by setting "consistent" option true/yes:

SIMPLE
{
    nNonOrthogonalCorrectors 0;
    consistent yes;
}

which relaxes the pressure in a "consistent" manner and additional
relaxation of the pressure is not generally necessary.  In addition
convergence of the p-U system is better and reliable with less
aggressive relaxation of the momentum equation, e.g. for the motorbike
tutorial:

relaxationFactors
{
    equations
    {
        U               0.9;
        k               0.7;
        omega           0.7;
    }
}

The cost per iteration is marginally higher but the convergence rate is
better so the number of iterations can be reduced.

The SIMPLEC algorithm also provides benefit for cases with large
body-forces, e.g. SRF, see tutorials/incompressible/SRFSimpleFoam/mixer
and feature request http://www.openfoam.org/mantisbt/view.php?id=1714

0a6ca7ae45 includeEtcEntry: New dictionary include directive: #includeEtc "etcFile"
Description
    Specify an etc file to include when reading dictionaries, expects a
    single string to follow.

    Searches for files from user/group/shipped directories.
    The search scheme allows for version-specific and
    version-independent files using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/\<VERSION\>
      - ~/.OpenFOAM/
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/\<VERSION\>
      - $WM_PROJECT_SITE
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/\<VERSION\>
      - $WM_PROJECT_INST_DIR/site/
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/

    An example of the \c \#includeEtc directive:
    \verbatim
        #includeEtc "etcFile"
    \endverbatim

    The usual expansion of environment variables and other constructs is
    retained.
