vagaikwa is on a distinguished road
Hello Guys,
I am trying to model a simple 2D channel, which has a circular particle and I am using moving mesh technique. I am not well conversant with moving mesh technique. Can someone please tell me how to implement this algorithm into my model. Can someone please help me with the UDFs..This is the link to the algorithm..

I think you have 1 way FSI here. You can write a UDF with DEFINE_CG_MOTION macro. In this this macro you can define x,y,z velocities and angular velocities. With the UDF you also enable the 'dynamic mesh' options.

I suggest you try to recreate some tutorial first. It will give you taste of whats happening.
