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...
