| Summary | 0003205: prghPressure BC uses hardcoded "rho" that fails with buoyantBoussinesqPimpleFoam | ||||
| Description | When trying to use the prghPressure BC with buoyantBoussinesqPimpleFoam it crashes with a failure to find rho. I tried what appeared to be an option in the tutorial of specifying "rho rhok;" in the p_rgh file BC, but that had no effect. I had to change "rho" to "rhok" in the PrghPressureFvPatchScalarField.C, and rebuild the finiteVolume library and then rebuild buoyantBoussinesqPimpleFoam with this library to see if it would work, and it does, but that is a very poor solution, just tried to make sure it works. I am new enough to OpenFOAM that I don't quite see what the current best approach to solving this is. I removed the "rho rhok;" mapping in the tutorial and it still worked, so it appears that things have changed since that tutorial was constructed. Maybe there is now a more robust method of handling this than creating a dictionary key that remaps rho to rhok, but if not, that is what I will probably do so that I don't need to have two versions around. This is essentially a duplicate of 3192, but that was closed for reasons that are not apparent, so I guess that I have to create this anew. | ||||

The prghPressure BC cannot be used with the buoyantBoussinesqPimpleFoam solver as it is an incompressible solver and hence does not have a density field in the standard sense but does have a constant reference "kinematic" density field rhok which is dimensionless. |
|
|
Maybe the best approach would be to rename the rhok field rho but to operate in an equivalent manner to rho it would need to be dimensioned and the equations changed. Basically this solver is not compatible with the standard compressible solver BCs and special versions of all of them would need to be created. We would rather get rid of the buoyantBoussinesqPimpleFoam solver altogether and we recommend using buoyantPimpleFoam instead with the Boussinesq equation of state. We will put buoyantBoussinesqPimpleFoam and buoyantBoussinesqSimpleFoam on the deprecated list. |
