Versions of NX Nastran Executable

Every version of Nastran has two different varieties— the LP and ILP—which determine how much memory can be allocated to the Nastran executable. Being able to identify the version you are using and switch between versions can be important because the ILP version may be required to solve some large models. Using the incorrect version of Nastran can result in an “Memory Request Exceeds LP-64 Limit of 2047 MW” error message.
