File name and directory path (248 characters maximum, including the characters needed for the directory path). An unspecified directory path defaults to the working directory; in this case, you can use all 248 characters for the file name.

The file name defaults to Jobname.

Filename extension (eight-character maximum).

If Fname is blank, the extension defaults to RST (for structural, fluid, or coupled-field analyses), to RTH (for thermal or electrical analyses), or to RMG (for magnetic analyses). For postprocessing contact results corresponding to the initial contact state in POST1, use the RCN extension.
