How to exert rotation (IMPDISP) on rigid bodies

Hi everyone. Today I was about to make a rigid cube rotate around Z axis of global system.

First, I set a master node on the surface of the cube and then made the nodes of this component subordinate to it. Then I exert IMPDISP (ZZ) on this master node.

The problem is, while Radioss completed the task without error, there is no anime output neither iteration record, just like no physical process in the simulation.

What the reason is? It's an urgent issue and could someone help me?

HM file is attached.

Hi Tainwang,

Good Morning!

I am Harish and helping to your query.

I quickly reviewed the model and found that, the error occur due to your entire model is rigid.

So try to have few elastic elements in the model.

Please update and let me know your comments.

Also let me know which version of HyperWorks you are using.

Hi Wang Tian

Then just create a few shell elastic elements out side the cube, i think this may helps and it will not take extra CPU time.

Please update the model and let me know your comments

Hi Harish

Thank you for your kind comment.

It seems that it's due to the rigid body set and after setting just one domain as rigid body, it worked.

Since I want to exert rotation on a part with 1,000,000 elements and I need to set as many as possible rigid bodies to save computation time. If a whole rigid part is impossible, what should I do?
