Hi there,

I am currently trying to do a magnetostatic simulation on a magnetorheological fluid brake for my thesis. I am trying to simulate total and directional magnetic flux density. I am getting an error saying Insufficient HPC Licenses available. Below is the full solution information. Also on another note if any one has any good tutorials regarding MR fluids and simulating the stress from the fluid flow and temperature etc that would be awesome.

As a guess, if you asked for 4 parallel but only 2 are available I'd try re-running with 2 parallel processes. The licence limits how many cpu can be used.
