Drill body rigid body.

Nozzles are deformable.

>>This can be done in WB LS-DYNA system by using Rigid Body Tools -> Rigid Body Additional Nodes.

there is no such function in WB:

 

>> Can you load your model (K file) into LS-PrePost and then click on Keyword Manager -> Model Check -> Contact Check -> Tied to check the tied status between the bits & drill? You can find the total number of nodes being tied from the check. Is this number reasonable?

Yes, I checked there, everything was fine. I added a few more faces to contacts and they started working.

Now I have another problem. Why does the tension between the nozzles and the case increase? Even when the body rotates through the air?
