Mesh can't be remeshed?
 

Hello,dear all: I try doning 2D dynamic mesh case,please see the mpeg file http://ounon.myweb.hinet.net/cell.mpeg

on plane in the box,I set it as a rigid body and import UDF finished. When I start to iterate,only these meshes that near the plane are deformed. Until different grids meet together,Fluent show me the message:"non-positive volumes exist" ; "update-Dynamic-Mesh failed.Negative cell volume detected"

How can I let all meshes of this box deformed?I had tried to change Layer/Smoothing/Remesh/ methods setting.Please help me find the problem,thanks a lot.

Best Regards, Jimmy Chan.
