[Other] Dynamic mesh dose not move correctly under oscillatingDisplacement condition

sakura_maru · March 1, 2016, 10:47

Hi all,

I would like to calculate piston moving by use of dynamic mesh. So, I checked pimpleDyMFoam tutorial of movingCone.

After that, I converted the tutorial of movingCone to full 3D model. I changed boundary condition to oscillate cone.

But after several step, the mesh broke suddenly.

Does anyone know where to fix?
Please see attached files and mesh_run.sh file.

Thanks a lot for your help!

Hi,

That "slip" condition for the pointDisplacement at the cylinder patch looks really suspicious. I believe that may be the problem.
