Hi,
Did you run your simulation using our SMALL server (16 CPU cores, 32 GB RAM) or the LARGE server (48 CPU cores, 96 GB RAM)?
Also, could you let us know the total number of cells in your simulation?
As a general suggestion for optimizing memory usage, you can start by running a simulation with a coarse grid to identify regions where the fields are negligible. Based on this, you can adjust the grid padding settings to exclude those body regions from the simulation domain, effectively "cropping" unnecessary areas and reducing the computational load.
