cermmid Posted 4 hours ago Share Posted 4 hours ago Hello, I'm using MPM solver. I'm using cutom noise ramp to mulitply E attribute. When mpm source is set to chunky it works. When I switch it to sandy, wich also have E attribute, when I run the sim I get errot that says NAN particle velocities were detected during integration! When I turn off noise ramp on E, everything works fine. I don't get it why multiplying E causes this. Any body knows a work around or had the same issue?

cermmid Posted 1 hour ago Author Share Posted 1 hour ago ok, I've found out, it get's this error when E gets value 0 from multiplication. If lowest number is bigger than that, it works. Quote Link to comment Share on other sites More sharing options...
