Sparse Matrix Solver Error Code 49

      Hello all,

      My team and I are attempting to run an Ansys Mechanical Workbench simulation on our University's supercomputer. We know that this computer is exceptionally powerful, and that other student teams have run very complex simulations, but ours consistently crashes. Below, I have attached screenshots of the error output in the solve.out file. For additional context, we are trying to run a variety of loading conditions on a solar vehicle frame design, with a mesh size of 5mm. Any help you could provide would be greatly appreciated.

      Try a starting the solver with 8 cores (np=8) to see if that runs without error.

      Following as I have encountered the same error.

      The solution works with 44 core, but fails with any more. The PC has 4x 22core CPUs.
