I have Nx7.5, 16 GB memory (RAM), DeLL work station, SSD
in NXNSTRAN > BIN >..
there are
LP solvers, which can address max 8 GB RAM, and it works fine
Nastran.exe
nastran64.exe

ILP solvers, which can address max 1 TB of RAM, and I can't make them works
nastranw.exe
nastranw64.exe

I made switch from Nastran.exe to nastranw(64).exe in customer default and "solve > edit solver parameter > solver executable (disabled "use environment variable UGII_NX_NASTRAN" > click at user specified > pointed to nastranw64.exe > OK > change memory to 10 GB

NOTE: on the same window where is memory are
solution monitor = check mark
old = no check mark
scretch = yes
sdirectory is assigned (40 GB space)

OK

DID NOT WORK

What is wrong?

To use the ILP solver from Femap, go to File/Preferences/ and select the "interface tab";
now check the box labeled "use ILP 64bit NX Nastran"

The ILP solver will be used for jobs submitted while this preference is set. No other changes required.

We may need to clarify some terminology, this is the Femap Forum. Are you running Femap? what version? If you are running NX then try their forum.

If you want to use the ILP executable with env variables then the file is :
nastran64L.exe
