Hi, everyone. I'm trying to conduct a simulation of a drop test. Currently, I am dealing with an error called "forrtl: severe (157): Program Exception - access violation" in my LS Program Manager. I have attached a picture of my simulation. If anyone knows how to deal with this error, please let me know!
Hi, I just solved the same problem. My solver is R13 SMP with single precision, it always goes wrong on the same simulation. When I changed the precision from single to double, this problem was just disappeared and simulation goes well. I hope can help you!

Main areas of problems seems to be:
Contact issue
Material issue
Occurs more often in SMP than MPP
Occurs more often in single precision than double
