Running HFSS simulation / optimetrics, and as you can see in the screen shots below, it completes first couple variations (optimetrics) then gives this error! This only happens when GPU is enabled (3 tasks, HPC config shown in the images below).
Is this really a license issue? Maybe in the middle of the simulation, for a certain variation, the computational load is too much that the GPU kicks in and gives this error?! It also helps to know when does the GPU kick in and so when it is useful computationally.
