Moldflow is RAM-hungry. A 3D mesh of 2 million tetrahedral elements can easily require 16-32 GB of RAM. If your physical RAM is full, Windows uses a page file on the SSD/HDD. If the page file is too small or the drive is full, Windows denies memory allocation requests. The Moldflow solver, unable to allocate memory, crashes with Error 99998.

But in simulation terms, the solver failed to meet the —a tiny internal threshold for how much the pressure or temperature can change between iterations. Moldflow is RAM-hungry
