Hi,
Just took a look at the mesh. The issue here is that it contains a lot of non-manifold structures: most edges in the mesh are shared by more than 2 triangles. For instance a shape like this (an edge shared by 5 faces) can't exist in the real world, so it cannot be simulated:

Non-manifold meshes are not supported by Obi, as explained in the manual (quote):

Although Obi will try to do its best handling non-manifoldness, extreme cases like this one can cause crashes/hangs. You must make sure your mesh is 2-manifold.
kind regards,
Edit: if you're unsure of what mesh manifoldness is, you can find a lot of info online. This is a good one: https://sinestesia.co/blog/tutorials/non...-fix-them/

Quote:Non-manifold meshes are not supported, if you use one the blueprint will try to identify the source of non-manifoldness and let you know via a warning message. Some non-manifold meshes will however slip trough, causing trouble down the road. Make sure that your input mesh is 2-manifold. In case you need to simulate a non-manifold mesh, use proxies.
