SPG Section not working
I am trying to run an example file from LSTC with an SPG section. I get the below error every time. When I change the section from SPG to a normal solid, everything works. Any help?
forrtl: severe (157): Program Exception - access violation

I know this is 5 months late but if you ever have issues with "forrtl:severe (157): Program Exception - access violation" try running the simulation with double precision. This is in the name of the version of ls-dyna labeled as "_d_" and comes after _smp_ or _mpp_. If that doesn't help then you can try a newer version of dyna or check that there are no issues with the contacts in your simulation.
