Hi all.
I'm simulating drilling. The first time I made a model as in the test version of LSTC:
Everything worked.
Now I made another model, in the form of a drill tip for concrete. And when I set rotation to the upper segment of the drill, the mesh is distorted. Why? I use exactly the same settings when I used a model like the LSTC. In the LSTC model, the drill did not touch the SPG (not lagrange mesh) die, but in the new model I made contact, could this be a problem? But if I turn off rotation and leave only translation, the drill doesn't distort:
I tried to build a grid in prepost or in third-party applications, the result is the same, there is no rotation. I also tried adding a cylinder and rotating it, that didn't help either:
HELP PLEASE
