Hello,

I am performing an operation akin to forming-springback-cutting using an SPH part. In reality, it is an impact followed by a slow speed material test, so the SPH part undergoes large deformations.

I'm attempting a multi-stage simulation, but the second simulation always terminates with some form of a system or MPP error during initalization. I've tried adding a long damping period to the first test, and have also tried explicit dynamic relaxation and implicit springback using both restarts and dynain methods. However, whatever I do the "cutting" simulation never runs past initialization.
