Summary | 0001359: Different fvc::div(phi,U) in staticFvMesh and rotatingMotion simulation with omega=0 | ||||
Description | I got very different results in a pimpleDyMFoam simulation with a staticFvMesh and a solidBodyMotionFvMesh (rotatingMotion with omega=0). The staticFvMesh results were identical to the pimpleFoam solution. The difference seemed to be caused in fvc::div(phi,U) with schemes like vanLeer or linearUpwind. The standard upwind or linear scheme give identical results in both cases. | ||||
Steps To Reproduce | Execute the uploaded application for the attached case and compare the result of fvDivPhiU at the first time step (0.002) in the staticFvMesh and the solidBodyMotionFvMesh simulation. Especially cell 421 shows very different results. | ||||

The results of the propeller tutorial seem to be identical for both setups. Maybe it's only a problem in the fvc and not in the fvm implementation. |
|
There appears to be an issue with the consistency between the U, phi and boundary specification in your 0 directory. If you remove the phi field fvc::div(phi,U) evaluates the same for staticFvMesh and a solidBodyMotionFvMesh. |
|
Why do you want to update of the cyclicAMI connections at each time-step for a static mesh? |

|
Difference comes probably from the snGrads at the walls. U.boundaryField() on the rotor is different in the two cases. It's almost 0 in the omega=0 case and !=0 in the staticFvMesh case. |
|
It is not clear what is being attempted here and the behavior is not reproducible with standard released solvers and cases. It is likely that you will need to arrange direct support with the writing of your application. |
