How do I run MSC/Nastran in batch?
Interactive limits on the Origin 2000 are 15 minutes of CPU time and 500 Mb for memory. All jobs that exceed these limits will be stopped, and should be submitted through the batch system. A nastran script has been written to automate the process of submitting MSC/Nastran jobs to the batch system. All input files that run serially on a local workstation can be executed in parallel on the SGI Origin Array without any modifications. The nastran script will ask the user to define the number of processors for the MSC/Nastran job. In general, multi-processor jobs should be limited to 2-4 processor. Choosing the correct number of processors is a function of the number of degrees of freedom (dof) within the FEA domain. For more information on parallel jobs visit the NCSA MSC/Nastran page. Nastran requires at least one command line argument. The most common usage is: nastran input_file_name Type the following command for additional information: nastran help For on-line documentation type: nast
