Dear all, 


I found the solution. In MAPDL Launcher in the HPC tab, I had pre setup of Type of HPC Run:  Use Distributed Computing (DMP), MPI Type: INTEL MPI (default). This setup doesn't work regardless of Number of Processors. 

When I change MPI Type to MS MPI, I can run LS-DYNA but only with 1 processor, when I try to change it to 2 processors, I get the error: Capability ANSYS Academic Research LS-DYNA Parallel does not exist in the ANSYS licensing pool.

Also, when I change type of HPC Run to None, LS-DYNA works.

Can anybody explain the problem more into detail? From above I get that the license I use does not contain the ability to use more than 1 processor.
