Resolving the “Out of Core Memory” Error in MAPDL — Lesson 7

How do you improve performance when MAPDL gives an error message?

The memory allocation in MAPDL is dynamic, so if the solver is running optimally out-of-core, it’s because it could not allocate enough resources to run in-core. The first step would be to review the solve.out for the analysis and see what the memory numbers were, as there might not have been enough RAM to solve in-core. However, you can manually control the memory mode using BCSOPTION command.
