This looks like the same issue as:

Float overflow at des/cfnewvalues.f:539 running SQP simulation

Please use a more descriptive topic title so that other users may search the forum for answers. Instead of “MFiX Solver crashed” something like “Float overflow in DEM-SQP case” (I modified the topic title already) As we have been learning (see the SQP Megathread), the superquadric code tends to produce extremely large numeric values, often leading to overflows. This, I believe, is largely due to “overshoots” in the Newton-Raphson successive-approximation scheme used to detect particle-p…
