Dear Alfr,
Nastran is executed with a command called nastran. The nastran command permits the specification of keywords used to request options affecting the nastran job execution. The format of the nastran command is:
where "input_data_file" is the name of the file containing the input data and keywordi=valuei is one or more optional keyword assignment arguments. For example, tu run a job using the data file example1.dat, open a MS-DOS window and enter the following command:
nastran example1.dat
For available keywords please check your Nastran Quick Reference Guide, you have many to use. A typical keyword is memory=memory_size, where memory_size is the amount of open core memory to allocate to nastran, for instance mem=1024mb.
