Issue with wedge domains #6
Comments
Dear hinman-stf, blockMeshDict seems uncorrect. When I run the blockMesh command in your case, I see topology errors. Best regards, Victoria |
The mesh was made using pointwise. You do not need to rerun the mesh. Just
the solver.

This is the same case:

Yes, I see. Good. |
Yes. Sorry. The case was originally set up for rhoCentralFoam. I quickly
swapped it over to test the wedge domain issue brought to my attention by a
student. This should not make a difference for the issue.

Next, one more correction: please change "sensibleInternalEnergy" to
"sensibleEnthalpy" in the thermophysicalProperties dictionary.

There seems to be an issue regarding pimpleCentralFoam with wedge domains. To replicate, please run the attached case. This is a standard benchmark case for supersonic compressible solvers. The grid is uniform and is wedge type. Using rhoCentralFoam the solution is correct. Using pimpleCentralFoam, there is an odd spurious jet type phenomenon along the central axis.
The issue is independent of flux scheme (have tried VanLeer and VanAlbada) as well as local time stepping, Euler or backward time stepping, or significant changes in CFL. This indicates to me it is a bug in the flux formulation when dealing with the wedge (empty) central axis boundary.

I am running this suite of solvers with OpenFOAM 6.
