dear all:
I'm working on 3D IC engine simulation.

I creat mesh in gambit which include 2 zone.one is hex ,the other is tet.shown in picture 1.

then I import the mesh into gambit.set parameters in DM model as follow:
Remeshingnly enable 'must improve skewness'.and 'maximum cell skewness' 0.9.

In cylinder: cutoff:0.5

then,set zone parameter as follows:
1.tet zone:deforming.
2.hex zone:rigid body,piston limit.
3.buttom of hex zone:rigid body,piston full.
4.outside of the tet zone:deforming.

but when I save the cas file and start mesh motion.I gained the picture shown in picture 2 and picture 3.

you can see the tet zone did not deform as well as it's out side for the did not deform during the mesh motion.

could anybody tell me why?

thanks in advance!
