Dear Travis, You don't mention if you are running NX NASTRAN from FEMAP or from NX Advanced Simulation. Check you environment variables, open a MS-DOS command prompt and write: SET and click ENTER, you will see the list of your environment variables. If running NX AdvSim check the correct address: UGII_NX_NASTRAN=D:\NX85\NXNASTRAN\bin\nastran.exe UGII_NX_NASTRAN_VERSION=8.5 Best regards, Blas.
Dear Travis, You need to create the above two variables at the OPERATING SYSTEM level, you need to go to "CONTROL PANEL > SYSTEM > ADVANCED CONFIGURATION > ENVIRONMENT VARIABLES" and there INPUT by hand the mentioned variables, pointing to the correct address:
Also in NX you need to go to "FILE > UTILITIES > CUSTOMER DEFAULTS > SIMULATION > NX NASTRAN" and define the settings for the solver: here you can enter the address explicitely or use the above commented environment variables, up to you. This way when you define a simulation always will use the above parameters
If you have created old studies where a WRONG solver address exist, simply click in the study name and select EDIT SOLVER PARAMETERS, here you can enter the correct address for th solver, ¿OK?.
