SOL601 exit due to insufficient allocation of Memory

[Uday029]

I have submitted a contact analysis using SOL601 from the Graphics window of NX CAE.And I got the following error and the run comes out. I have been pasting the corresponding log file. Please guide me.

Hello!,
You are running the LP-64 solver of NX NASTRAN that is limited to 8 GB, and you use the nastran keyboard MEM=8GB, then the error. Either use the ILP-64 solver with bytes per word = 8, or better reduce the memory assigned to the solver using say MEM=5GB

The amount of memory needed by the solver is output in the *.F04 file. Important values are: (a) minimum memory required, (b) memory required to avoid spill, and (c) memory available. An excerpt is shown below:

Best regards,
Blas.
