After you have specified the load step options and analysis options, use the SAVE command to save your database contents to a backup file.
Backing up your database prevents your model from being lost should your computer system fail. If you need to retrieve your model, use the RESUME command.
To start the solution, use the LSSOLVE command. If you prefer, you can create and solve multiple load steps using array parameters or using the multiple solve method. For information about these methods, see the Basic Analysis Guide.
To finish your solution and exit from the SOLUTION processor, use the FINISH command.
