In Windows, Autodyn will use the user temporary folder for temporary
   files and log file creation. The local user must have read/write permission to this folder. The
   location of this folder in Windows 7 systems is
     C:\Users\username\AppData\Local\Temp. On Linux,
   temporary session files and log files are written to the model data folder.
