Dynamic Mesh
 

Hello Guys,
I am doing a dynamic mesh simulation in2D in FLUENT 6.3.26.
My geometry is simple 2D channel and I have a circular particle which should move.
I am using the DEFINE_CG_MOTION UDF where in my particle move because of the pressure difference. I have created periodic boundaries.
I am using smoothing and remeshing mesh methods for dynamic mesh parameters.
I have used Rigid Body type and loaded the DEFINE_CG_MOTION UDF.
When I display the grid and try to preview the zone motion it does not show my particle moving.
Is there any problem in setting up my model? Please give me some hints and tips as I am new to this model. Any help is highly appreciated. Thanks.
