I have created a cloth mesh, should be a top for victoria 3 and 4. Now i can create it as a conforming or as a dynamic cloth. I have decide to do the last.

Now comes the problem. Everytime i start the cloth simulation poser never comes to an end.
The 'calculation dynamics' screen appears but never disappears, not after hours ...

The progress bar is empty all the time.

What can i to against this problem ?
