engine-mesh, layer removal?
 
I made a case to run with dieselEngineFoam(kivaTest+aachenBomb). Everything is ok but mesh. I started the simulation at BDC. At TDC I have a deformed mesh with the same number of cells. There is no layer removal.
-would you please guide me to set the case correctly.
-should I change the code or do any pre-processing?

Thank you

Hello,

u have to implement the engineTopoChangerMesh class

engineTopoChangerMesh layerAR; instead of

engineMesh layered;

in the engineGeometry file. Define delta and offset and min/maxlayerthickness for your calculation. That should be almost all.

If u have more questions please search for papers from Tommaso Lucchini.

regards
