  1. I am trying to sim a 1000 frames of a FEM coral with branches swaying in water currents. For some reason it freezes at frame 800. I checked all the DOP nodes, and couldn't find anything obvious. What am I missing? softCoral.FEM.paintWidth.h16p5p378.v27.hipnc
  2. I'm trying to simulate some relatively complex interactions between a squidgy, soft-body tentacle kind of asset and some arbitrary, sort-of-complex geometry. FEM seems like the best way to go about this - I've tried cloth simulation, but but there's little else that easily gives me the really nice volume-preserving properties I get out of the soft-body solver. Overall though I'm still kind of a noob at this, so I'd appreciate completely different suggestions on how to do this My main problem is that no matter what I do, I seem to very easily get tets being stuck on concave geometry. I'm attaching a scene that I've been using as a technical test to try and resolve the issue - it's pretty representative of the issues I get on more complicated scenes, but with faster iteration times. The objective is to get this sea cucumber to pass through a narrow, concave space in an organic, slippery, squishy way. Mostly it behaves correctly, but the problem is that eventually: Some of the tets will get weirdly stuck on the geometry The unfortunate thing is that increasing substeps and collision passes only seems to make this worse - with more collision passes, more tets seem to get stuck, and it becomes harder for them to get unstuck! I don't have any friction on either object, and ideally I'd want them to pass through each other really smoothly. Is there a good way of achieving that? Or anything substantially different I could be doing, to get the same effect? Would love any advice people might have! The scene itself: PenetrationTest_FEM.hip
