200*200*200 = 8 Million elements with roughly as many nodes. The error message says that it's requesting ~95 MB which is well within reason when you consider that each piece of data needs to occupy several bytes, and each node and element have several pieces of data each. You're going to need a l

Hi all, I am changing my code from 2D to 3D. But I am having problens with the memory usage. I mannage to create an example that reproduce the error. As we can I just generate the mesh and get all the memory. The interesting part is that when I run the code (for Nelx,Nely and Nelz>150) in 1 ,2
