How to execute a bidirectional mesh movement( FSI)
 

Hi,

I have a ball in the flow region, where I'm able to move it in a direction parallel to the flow. Now I have to move it in both radial as well as axial direction to the flow(DOF=2). The flow pushes the ball, actually. To simulate the real behaviour of the ball I have to move it in both directions(now) and all DOF actually after I complete this. Help me if you know to model it.

I gave macros for the movement for 2DOFs. There is no sign of convergence. Any other method to give the motion.

Thanks, Ganesan
