- relocated to dedicated foamVtkOutput namespace. Make it easier to
obtain a formatter directly without a foamVtkOutput::outputOptions.
Make the logic clear within outputOptions (avoid previous, cryptic
bit masking). foamVtkOutput::legacy also becomes a namespace instead
of a class. Relocate commonly used things into src/fileFormats, leave
volField-related parts in src/conversion.
Adds overset discretisation to selected physics:
- diffusion : overLaplacianDyMFoam
- incompressible steady : overSimpleFoam
- incompressible transient : overPimpleDyMFoam
- compressible transient: overRhoPimpleDyMFoam
- two-phase VOF: overInterDyMFoam
The overset method chosen is a parallel, fully implicit implementation
whereby the interpolation (from donor to acceptor) is inserted as an
adapted discretisation on the donor cells, such that the resulting matrix
can be solved using the standard linear solvers.
Above solvers come with a set of tutorials, showing how to create and set-up
simple simulations from scratch.
- Use on/off vs longer compressed/uncompressed.
For consistency, replaced yes/no with on/off.
- Avoid the combination of binary/compressed,
which is disallowed and provokes a warning anyhow
- By definition, binary STL uses float (not double) when reading.
The ascii STL should be the same. This reduces memory overhead when
loading files. The older triSurface reader had float, the surfMesh
reader had double, but now has float.
- Inconsistency in the STL merge-tolerances between triSurface reader,
surfMesh reader and WM_SP vs WM_DP. Now use consistent tolerances
conrresponding to 10,100 * doubleSMALL.
- Similar float/double code adjustments for TRI format since this is
very similar to the STL reader and had a similar inconsistency between
the triSurface and surfMesh version. The AC3D reader still uses
double when reading, but this can be revisited in the future (and can
then remove the stichTriangles method too).
- only treat text as an option if it is preceded by 0-4 spaces.
This prevents the description of an option from being accidentally
detected as an option.
Evolves an electrical potential equation
\f[
\grad \left( \sigma \grad V \right)
\f]
where \f$ V \f$ is electrical potential and \f$\sigma\f$ is the
electrical current
To provide a Joule heating contribution according to:
Differential form of Joule heating - power per unit volume:
\f[
\frac{d(P)}{d(V)} = J \cdot E
\f]
where \f$ J \f$ is the current density and \f$ E \f$ the electric
field.
If no magnetic field is present:
\f[
J = \sigma E
\f]
The electric field given by
\f[
E = \grad V
\f]
Therefore:
\f[
\frac{d(P)}{d(V)} = J \cdot E
= (sigma E) \cdot E
= (sigma \grad V) \cdot \grad V
\f]
Usage
Isotropic (scalar) electrical conductivity
\verbatim
jouleHeatingSourceCoeffs
{
anisotropicElectricalConductivity no;
// Optionally specify the conductivity as a function of
// temperature
// Note: if not supplied, this will be read from the time
// directory
sigma table
(
(273 1e5)
(1000 1e5)
);
}
\endverbatim
Anisotropic (vectorial) electrical conductivity
jouleHeatingSourceCoeffs
{
anisotropicElectricalConductivity yes;
coordinateSystem
{
type cartesian;
origin (0 0 0);
coordinateRotation
{
type axesRotation;
e1 (1 0 0);
e3 (0 0 1);
}
}
// Optionally specify sigma as a function of temperature
//sigma (31900 63800 127600);
//
//sigma table
//(
// (0 (0 0 0))
// (1000 (127600 127600 127600))
//);
}
Where:
\table
Property | Description | Required | Default
value
T | Name of temperature field | no | T
sigma | Electrical conductivity as a function of
temperature |no|
anisotropicElectricalConductivity | Anisotropic flag | yes |
\endtable
The electrical conductivity can be specified using either:
- If the \c sigma entry is present the electrical conductivity is
specified
as a function of temperature using a Function1 type
- If not present the sigma field will be read from file
- If the anisotropicElectricalConductivity flag is set to 'true',
sigma
should be specified as a vector quantity
2)Adapting divU in TEqn.H for compressibleInterDyMFoam and compressibleInterFoam
3)Re-instated sixDoFRigidBodyDisplacement as patch for pointFields. It allows to use a different fvDynamincMesh type
independently of the BC's
