Memory Issue

Please login with a confirmed email address before reporting spam

I am doing 3D simulation that is not symmetric, using the mf physics , coil geometry analysis and stationary study. Coil geometry analysis have 2,192,126 DOF and Stationary study have 19,338,394 DOF.

I have used domain wise mesh maximum upto fine and with a total of around 12 GB physical memory.

I am using segregated and iterative solver of stationary study. But my simulation is stucking. I am doing the simulation using i5 processor and 16 GB RAM. Further I have to do frequency analysis.

Can you tell is this the memory issue? If yes, how much is recommendable memory for this much DOF.

16 GB of RAM isn't very much for doing a problem that size. Consider modifying your geometry, mesh or both. Consider using linear discretization if you haven't already. See https://www.comsol.com/support/knowledgebase/1030
