Dear Foamers
I am attaching a simple 2D geometry where only the white edge is moving/sliding in the positive x direction. I tried the dynamicMotionSolver, I got correct motion but unusable mesh. I shifted to foam-extend to use the topoChanger, I tried the movingBodyTopoMesh, however it seems does not work for curved edges. May be I need to customize a topoChanger for this case. However, I want to hear your advice first. Regards |

Hi!
What if you create a cellzone around that curved edge to the top edge? And move the whole zone. Or check the displacementLayeredMotion. It is a bit tricky to use but really powerfull. But there can be many solutions for this problem. |

Hi simrego, Thanks for your reply. The main problem is that the upper edge is not a single straight line. Actually I think I've solved the problem using adding/removing layers modifier. First of All I divided the geometry to upper and lower parts (two meshes). Then I've created left and right cell zones on the lower parts and I moved the area between the left, right and the interface between lower and upper regions. I tried to use sliding interface between the two areas without success. For solving the physics I used GGI BC for the interface.. I am running the case right now .. let see Saleh |
