Yes, that's simply a mesh refinement. > > If the increased fill caused the system to run out of physical memory and > start swapping, then it would not be surprising for it to take days. It does not swap, it consume memory that I can handle, it just does nothing, or gets stuck somewhere. This is a toy problem, solved by PARDISO in no time. Dominik
