Hello

I am currently using Lumerical trial license for FDTD in order to decide if the research group I belong to buys some licenses.

Unfortunately during the trails I realized that Lumerical is only using 50% of the simulation PC resources. The specs are the following:

AMD EPYC 7702P

256GB RAM

My doubt is if there is a way to change this? I have already tried following the steps described at:

Ansys Insight: Determine the optimum resource configuration to run Lumerical FDTD simulations

also when I tried to increase the number of threads above 32 I get the following error:

"HQPD-BABY(process 0): Requested more than the 32 allowed HPC units provided by this license." is this error due to the trail license? or Lumerical is limited to 32 threads?

Thanks

You will need more solve/engine license if you want to run with more than 32 cores. See this article in our KB for details: Lumerical solve, accelerator and Ansys HPC license consumption ÔÇô Lumerical Support.
