I'm a bit new to Houdini and am trying to simulate a "fill power" test of the down feathers. Fill Power Test I can do this for a few spheres with the FEM system. However, this is slow and won't show the fibres... Would it be possible to do it in a fibre-like way? The down cluster looks like this: down cluster Each unit could be as simple as "a small core with many curves grown on it". I tried vellum hair, but it seems hard to attach the hair in a stiff way and have high stiffness. Also, I cannot make curved hair work, only straight lines. I'm considering the "wire" system at the moment. But most of the tutorials I can find online are for simulating ropes... I guess what I need is something similar to a "sphere with tree branches grown in all directions", and simulate a compression test with a lot of these spheres... My question is, is Houdini the right tool for something like this, and, what should be a good way to approach it?
