Dynamic mesh problem in gambit-fluent
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

do you have the UDF for this case and you want to hook it in fluent or you don't have anu UDF still?

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.
