Hi!
I've a general question about the modification of existing meshes. Is there another method of modification than a dynamic mesh udf? Because I need to modify my mesh after each 1000 iterations in a time steady calculation. I think dynamic mesh is only working in transient mode??? Thanks, Joe |

In the steady case, you can use the following macro to tell fluent to update the mesh as the "DEFINE_GRID_MOTION " or other mesh motion macros instruct at the end of each iteration. Of course, do not forget to hook it in fluent. DEFINE_EXECUTE_AT_END(update_mesh) { CX_Interpret_String("(steady-update-dynamic-mesh)"); } |

(steady-update-dynamic-mesh) is the scheme command to tell fluent update the steady dynamic mesh. |
