Dear All

I want to obtain a maxwell capacitance matrix of order (400x400) for my COMSOL model (in 2d-Axi geometry). While I run my simulation on a system with 16 GB RAM size, it is showing out of memory error. Even the same error is showing in a system having 64 GB RAM. I have used extremely coarse mesh in my model. Is there anything else that needs to be set in order to get the higher-order Maxwell matrix? Is there a limit to how big the maxwell matrix can be that COMSOL can calculate? So, how much RAM would be needed to get the same-sized Maxwell matrix?

Can someone please figure out what to do?
