As a side effect, this will produce some output in your execjob window like this:
Estimated buffsize=16385

Splitting scratch space to multiple files:
Note: The following option is not supported, and should only be used as a workaround.
If you cannot get your file system setup to support large files, the following workaround will allow you to split scratch space to multiple files:
2) The node RC file: <install_dir>\conf\net\<nodename>\nast705.rcf.<nodename> refers to the Windows name of the computer, which does not necessarily correspond with the TCP/IP node name for the computer. This file should be used to define parameters that are applied to all MSC/NASTRAN jobs running on this computer.
3) The system RC file: <install_dir>\conf\nast705.rcf.
This file should be used to define parameters that are applied to all MSC/NASTRAN
jobs run by an individual user. The HOMEDRIVE and HOMEPATH environment
variables are set automatically on Windows systems.
