remeshing for large mesh motion
 
2 Attachment(s)
hi there,
im trying to simulate free falling of a rigid ball into calm water with free surface.
i've created a 3d gtm mesh with one element thickness to have a 2d simulation. then imported into cfx-pre, wrote expressions for ball motion, and apply it on ball boundry.
then started cfx-solver, everything goes well until negative volume error after 200 iterations!
i've found that minimum value of "orthogonality angle" will drop below 1!

then i've read THIS tutorial about re-meshing and found that i have to do something with "replay manager" but this page is a brief overview and don't have detail information also i couldn't find a step by step solution for it :(
my problem is somehow the same as video in that tuutorial!
could someone please tell me how to do re-meshing?
