Isaac-Sim crashes when I tried to define a deformable body

Hi everyone!

I am trying to define a deformable body using a custom mesh. However, after I add the deformable body configuration, Isaac-Sim is shut down with the following error messages:

I attached a scene containing a minimal example and a video. Thank you in advance.

Thanks for reporting, following up with the physics team to see if there is a solution

Can you please provide us with the referenced model that actually does cause the crash? The provided usd file does not contain the troublesome mesh.

@AlesBorovicka, sure!

Thanks I was able to repro the crash and created internal Jira ticket to fix that.
