Issue in the “Simple Restart” using MPP solver

      I want to restart a LS DYNA mpp simulation, I have d3dump files. It is going to be a simple restart. I have done restarts before due to power failure or other reasons. For some reason, this time it does not work.

      I keep getting error code 157.

      My expression was : mpiexec -np $NCPU -aa -a "$SOLVER" R=d3dump01 memory=$MEMORY

      I made sure that all parameters were kept constant.
