  1. Is it possible to enable auto-save by default so I don't have to toggle it on at the beginning of each session? It is so easy to forget...
  2. Methods for assigning attributes to a tetrahedral mesh

    Thanks so much Konstantin! That's a very interesting approach. Wouldn't have thought of that on my own. I will definitely play around with the HIP file you attached.
  3. I'm looking for alternative workflows for defining attributes on a tet mesh for FEM simulation. Normally I would use intersecting volumes to define regions inside a tet mesh. But for my current purposes that would require producing some pretty complex geometry. The ability to paint these attributes would be simpler. For instance, it might be nice to be able to paint an attribute on the surface and have it penetrate the tet points at a given depth. (Though even if that were possible, I'm not sure how you would access deeply interior points that are not close enough to the surface.) What methods do you use for assigning attributes to a tet mesh?
  4. In the vellum constraint features masterclass, John Lynch says that FEM is more accurate for solving objects with high elasticity, but he doesn't elaborate on that. I'm curious about more specifically when you would reach for the FEM solver over vellum's tet softbodies. I am familiar with tet softbodies, but not with FEM. Is FEM better at achieving certain effects? Anything about the FEM workflow that is better in certain situations? Is FEM just more accurate from a technical perspective, or do you think it actually gives better results?
  5. Thanks so much! That's exactly what I was looking for.
  6. I'm trying to understand how to assign colliders to objects in a vellum simulation. For example, I would like to add a collider that only grains will collide with, while the collider is ignored by other objects in the simulation. This helpful solution shows how to accomplish this with a dopnet setup. (A screenshot of this approach is below.) However, I don't know whether it's possible to send the output of the dopnet to Vellum IO and Vellum Postprocess. Is there another way around this? Or perhaps a way to control collisions from within the vellum sop solver?
