15198a34bd fluxRequired: Added setFluxRequired function to fvSchemes class 
Added calls to setFluxRequired for p in all incompressible solvers which
avoids the need to add fluxRequired entries in fvSchemes dictionary.

Will add calls to setFluxRequired to the rest of the solvers.

0ce5742d6a saturationModels: Added a model for constant pSat and Tsat 2015-07-04 14:48:19 +01:00

a752d3e588 saturationModels: Added Tsat function 
Currently this is implemented only for the Antoine equation, for the
other more complex models an iterative inversion from pressure to
temperature is required.

d0f15d4e3c EEqn: Added rho*(U&g) source term 
Generally this term has a VERY small effect on temperature, it is only
important for low-speed buoyancy-dominated flows.

60cffb2fc3 pimpleFoam family: Added PIMPLEC (PIMPLE-consistent) support 
Select using the optional

    consistent true;

setting in the PIMPLE dictionary of fvSolution.

This option is generally only beneficial for cases run in PIMPLE-mode
with a large maximum Courant number.

Select LTS via the ddtScheme:

    ddtSchemes
    {
        default         localEuler rDeltaT;
    }

The LTS algorithm is currently controlled with the standard settings in
controlDict, e.g.:

    maxCo           0.5;
    maxDeltaT       2e-8;

with the addition of the optional rDeltaT smoothing coefficient:

    rDeltaTSmoothingCoeff 0.02;

which defaults to 0.02.

    ddtSchemes
    {
        default         localEuler rDeltaT;
    }

e00ae44ad0 interFoam family: Added run-time selectable LTS support 
LTS is selected by the ddt scheme e.g. in the
tutorials/multiphase/interFoam/ras/DTCHull case:

ddtSchemes
{
    default         localEuler rDeltaT;
}

LTSInterFoam is no longer needed now that interFoam includes LTS
support.

91ee15e3ac rhoCentralFoam: Added experimental LTS support 
Select LTS via the ddtScheme:

ddtSchemes
{
    default         localEuler rDeltaT;
}

The LTS algorithm is controlled with the standard settings in
controlDict, e.g.:

maxCo           0.5;
maxDeltaT       2e-8;

with the addition of the optional rDeltaT smoothing coefficient:

rDeltaTSmoothingCoeff 0.02;

which defaults to 0.02.

For cases with reasonably uniform meshes like the forwardStep tutorial
LTS does not provide much benefit but for cases with large variation in
cell-size like the biconic25-55Run35 tutorial LTS provides significant
speed-up to convergence particularly if started from uniform conditions.

80e13f8002 rhoCentralFoam: Reverted correction to BCs 
Reverted changes proposed in
http://openfoam.org/mantisbt/view.php?id=1548 as it adversely affects
fixed-value BCs and is formulated to fix an issue with an unphysical
case.  Further analysis of the handling of fixed pressure outlet
conditions as the Mach number approaches 1 is required.
