I wanted to ask a few questions regarding HFSS. Specifically, I wanted to ask for some clarification on what exactly does "out-of-core" mode does, and are there settings regarding "out-of-core" mode that we can access/modify. Currently in HPC options I only see the option to either enable to disable "out-of-core" mode, but no other settings. Additionally, for larger simulations, for example requiring 64 GB of RAM or more, would it also be possible to run these simulations instead with less memory (less than 64 GB) and a large SSD? Specifically, what is the difference/benefit of solving purely on RAM versus using smaller RAM in conjunction with a large SSD?
