Simulating Particle motion in tube using UDF
 
Hi friends

I want to simulate moving a particle in a tube of water. I want to use UDF, Is there any one have any simple example of this type of UDF files?
or any body know which macro better to use?
CG_MOTION or SDOF ?

Hi
I think that your case will not require to UDF!
You can use the Injection option of Define meno in fluent for tail the one or more particle.

yes, it's a rigid body, a rigid ball which it's diameter is half of tube's diameter
