the length of the command line...
I have encountered this message after restarting LS-DYNA by d3dump file:
"the length of the command line arguments is too long and exeeds the limitation! "
then LS_DYNA doesn't run.
Please help me this regard.
As a test, try moving your model to a shorter path (folder in C: if local) and shorten your file name. See if that works.
If you are in the Windows world, then also make sure there are no spaces in the new shorter path.
