Ever wondered how to get your MSC Nastran to run faster? Check this and see if it helps you, especially for large solid models.
Inserting the following Nastran System Cell Cards has helped me.
NASTRAN BUFFSIZE=65537
NASTRAN SYSTEM (151)=1
You could also look at using*:
NASTRAN ITER = YES
* Use this only when you have very large solid models and it is better to validate the the usage of Iterative Solvers by running some check problems to get confidence in Iterative Solvers.
Finally, depending on the memory available you could use the following in command line
mem=60% of Available Memory
E.g: mem=8gb
Run more simulations...

A bit unrelated but I am hoping you can help.
I have problem that I am working on.I am using PATRAN to submit the job to NASTRAN.It looks like NASTRAN solves the problem but my .f06 file reads as follows:
*** USER FATAL MESSAGE 1019 (OPNPFL)
FORTRAN UNIT OPEN ERROR
IOSTAT = 3, No error (errno=0)
As for my .f04 file, its just empty.Also,when I try to read results, there is no xdb file created.Can you please help? Thank you.
İ solved my problem thanks to you.
Thank you very much..
