Rigid Body mesh deforms
 
2 Attachment(s)
Hi, I have problem with rigid body movement. After about 500 steps the rigid body tends to deform. I have no idea how to fix it.

It is actually a 3D domain, but very thin.

Rigid body is defined by four faces, grouped under name ns_kast.
wall-sein_auguga and interior-sein_auguga are both automatically generated by Fluent and defined as deforming.

Remeshing works fine when Rigid Body moves periodically up and down (defined by UDF). But it is not rigid, it deteoriates over time. Any ideas?
