Dear all,
I am trying to simulate the problem where a 3d cylindrical pipe, whose wall is expanding and contracting simultaneously in a sinusoidal manner. How to put the velocity components for that situation using DEFINE_CG_MOTION macro. Any help is highly appreciated. |

Hi moloykb,
I'm currently experiencing the same issue : DEFINE_GRID_MOTION on a cell block , for the mesh movement it's OK , but I've a 0 velocity on the moving wall , so a wrong shear stress... Did you solve this ? Regards Ben |
