Default dynamic meshing : an err message

Posts: n/a
Hi All,

I am running a case with dynamic meshing utility. I frequently get following error message :

************************************************** ** Updating mesh to time 1.00000e-02 (step = 00001) Warning: multiple subdivision required on zone 12. Warning: multiple subdivision required on zone 13. Warning: multiple subdivision required on zone 14. Warning: multiple subdivision required on zone 15. Error: Internal error at line 1593 in file 'grid.c'. replace_c_in_f: cell not found Error Object: () ************************************************** **

Where the zones mentioned are moving walls, defined as rigid body and motioned using an udf.

Fluent updates the mesh, but, mesh gets highly skewed and it ends with the above err message.

Thanks and Regards, Prasad Laxman kane

if you have meshes around the wall,you'd better use the interfaces to avoid the problems caused by the linked mesh. try it &good luck!
