Hello Friends,
I want to simulate flow induced rotation of a turbine kept inside a shell. i have meshed the volume in gambit. i read one tutorial , in which for solving dynamic meshing problems we have to call a UDF. i dont have any idea about compiling UDF for a particular problem. Can somebody guide how to compile an UDF for this problem?
thanks in advance

Hi Jeya
You must use CG_motion macro in your UDF. I suggest that you read fluent udf manual
Also remeshing is simple method in dynamic mesh that you can use.
