Hi,

I have a basic question: The new ANSYS-Lumerical licenses are of 32 core limit. Previously, Lumerical installation on the cluster was done and I was able to use 100 nodes x 68 cores. Now, if I purchase the 32 core limit license, does it mean that I can use only 1 node x 32 cores, or can I still use 100 nodes x 32 cores? If anyone can answer this question, it would really help me out.

Thanks in advance,

With the new Ansys licensing, for 1 FDTD solve license, can run one (1) simulation regardless of the number of nodes up to a max of 32 cores/processes. Additional solve licenses is required per additional 32 core increments. See this article for details.

Hi Lito,
Thank you for the verification. We usually run intense simulations on the cluster (We use 16 nodes x 68 cores/node = 1088 cores in total) for a simulation. To verify, now using 1 FDTD solve license, we can use only 32 cores (not 32 cores/node). Is my understanding right? What do I need to do if I need much higher compute requirements?

Yes up to maximum of 32 cores. You will need 34 FDTD solve licenses to run an FDTD simulation for a total of 1088 cores (1088/32=34). Contact your Ansys account manager if you want to purchase additional "FDTD solve" license. Product name: "FDTD Accelerator". Unlike the full FDTD license, this is a "FDTD solve" only license and does not come with the "FDTD GUI" license.
