That was my thought. You have some issue with Intel MPI, so if you try another MPI (MS MPI in this case), it may work.

What's the LS-Dyna/ANSYS version you are using ? You are supposed to be able to solve with at least 4 cores without pulling any extra license.

The 'None' mode just simply means you are not solving it in distributed mode, but rather the shared-memory mode. For this mode, MPI is not used, so you avoid MPI issue that way.
