Problems with large meshes
Posted: 17 Jul 2015, 11:14
Hello,
I am currently trying to run a large (read: ice sheet sized) simulation, which demands a fairly fine resolution mesh. I am having problems with Mumps when using the Navier Stokes solver:
From what I understand, the problem is related to the amount of memory allotted to Mumps, and there is a keyword available to increase it.
This did indeed fix the problem with some of my tests, but when I scaled up the mesh size, it still did not work. Any advice?
