  1. I'm trying to use the FEM solver for a car crash destruction and I need some pointers or tips. The effect is looking great for about 5 frames after the crash, but after about 15 frames the car returns back to it's original shape, which is not what I want. Which leads me to Question #1: How can I keep that crashed shape without simply animating the whole object's Damping Ratio? If I do animate the damping ratio to be an absurdly high value after the crash, the effect works great for the crashed area but the car loses all of its kinetic motion and the car just stops. I've tried to use the SOP Solver to set attributes on the FEM geo but this doesn't seem to be working, so Question #2: Are the FEM and SOP solvers incompatible? It's very possible that I'm not wiring these correctly, but it seems like the SOP solver is not correctly reading the FEM data, after about 8 frames the SOP solver gives me a warning saying that it fetched old data and it doesn't seem to be capable of viewing the entire animation. Also I don't seem to be able to set primitive attributes like soliddampingratio and have it work correctly in the FEM solver. Is this help page out of date with H16.5? Basically what I think I want is for the Damping Ratio or the Shape Stiffness to be drastically raised for the primitives where there is crash damage and I would like the solver to see the crashed shape as the new rest shape so it no longer returns back to its original state. Thanks in advance for any help on this. And to anyone wondering about using other solvers (cloth or wire) I've found that the FEM solver gives me the best crash results because of the volume preservation.
