Hello,

i am still working/searching for a good solution for MeshMoving. I figured out that the Cut/adding-cell algorithm can be find in the LayerAR.C (with its baseclasses).
For testing I took the DieselEngineFoamSolver with "EngineTopoChangerMesh.H" (instead of EngineMesh.H) and "CreateEngineDynmiacMesh.H" (instead of CreateEngineMesh.H).

For the first loops (crank angle -180 - (-170.5)) all is done fine. But then the solver gives the following message when the crank angle exactly reaching -170:

deformSwitch 20
INFO 0
PistonDeformation0
Piston layering mode
01
1
MinLayerThickness 0.003
Segmentation fault

Normally there is :

deformSwitch 20
INFO 0
PistonDeformation0
Piston layering mode
01
1
MinLayerThickness 0.003
2
3
3
....

In the source code at this point: (layerAR.C)

Info << "1" << endl;
Info << "MinLayerThickness " << minLayerThickness << endl;
autoPtr<mapPolyMesh> topoChangeMap = topoChanger_.changeMesh();
 
Info << "2"

For me it seems to be a memory error ? I am not the C++ pro, just basic solid skills.

I would be very happy anybody can help me! Any have fun to decrypt my Enlish
