Hello,

I am attempting to run an impact simulation in LS-DYNA and I keep getting error 70021. Upon Googling the error, it seems to be a memory problem, but I have not yet found a way to fix it. So far I have tried to clean up the model, and gone to the Analysis Settings --> CPU and Memory Management --> Memory Allocation and increasing the value there. Neither has worked so far. What else can I try?

Thank you.
