Starting and Exiting a CAE Fidesys Session

The following commands are used to control CAE Fidesys execution.

Starting the Session

The command line version of CAE Fidesys can be started on UNIX machines by typing "CAE Fidesys" at the command prompt from within the CAE Fidesys directory. If you have not yet installed CAE Fidesys, instructions for doing so can be found in Licensing, Distribution and Installation. A CAE Fidesys console window will appear which tells the user which CAE Fidesys version is being run and the most recent revision date. A graphics window will also appear unless you are running with the -nographics option. For a complete list of startup options see the Execution Command Syntax section of this document. CAE Fidesys can also be run with initialization files or in batch mode.

Windows File Association

Windows users have the option to associate .cub, .sat, and .jou files with CAE Fidesys. This means that double-clicking on one of these files will open it automatically in CAE Fidesys. This option is available during the installation process.

Exiting the Session

The CAE Fidesys session can be discontinued with either of the following commands:

Exit

Quit

Resetting the Session

A reset of CAE Fidesys will clear the CAE Fidesys database of the current geometry and mesh model, allowing the user to begin a new session without exiting CAE Fidesys. This is accomplished with the command:

Reset [Genesis | Block | Nodeset | Sideset]

A subset of portions of the CAE Fidesys database to be reset can be designated using the qualifiers listed. Advanced options controlled with the Set command are not reset.

You can also reset the number of errors in the current CAE Fidesys session, using the command:

Reset Errors <value>

which will set the error count to the specified value, or zero if the value is left blank.

Abort Handling

In the event of a crash, CAE Fidesys will attempt to save the current mesh as "crashbackup.cub" in the current working directory just before it exits.

To disable saving of the crashbackup.cub file set an environment variable fidesys_NO_CRASHSAVE equal to true. Or, use the following command:

Set Crash Save [On|Off]

This command will turn on or off crashbackup.cub creation during a crash on a per-instance basis. To minimize the effects of unexpected aborts, use CAE Fidesys automatic journaling feature, and remember to save your model often.
