Calle is on a distinguished road
i am working with FLUENT at the moment, to simulate a left ventricular contraction.

Normaly i would use different meshes of the LV at different times of a real contraction but unfortenatly i cant do this right now.
Here is my question, does anyone know how to set up something like a contraction. My basic idea is to just take the wall of the LV and move every point to the middle(or a specific point) of the LV at the same speed going reverse after time. Is this even possible to move the wall to a defined point?

I searched for different UDF's but couldnt find a answer for my problem.
I thing i have to use the define_cg_motion macro or just a grid_motion macro to solve my problem.

Maybe anyone can help me with that problem.
If not, does someone own a list of possible commands for UDF's under c? I never used UDF's or worked with c so i dont know much about possible commands or tricks to set up the motion!

With best regarts
