Simcenter Madymo Simcenter Madymo - How to use MADYMO_RESTART

General:

Madymo Restart functionality allows the user to continue a Madymo run from particular points in time. This functionality helps user to reduce overall simulation time in safety assessment studies. Below are the main steps described to apply restart.

Step 1: 

Restart function requires binary files which contains complete record of the model. Set the time interval in TIME_STEP_RESTART. This will store the simulation state dumps into the .rst file when the simulation model is run.

Step 2:

For a restart analyses a input file needs to be created with root element MADYMO_RESTART.  The restart template can be loaded within XMADgic by File-> "New..." 

Select "MADYMO _RESTART"  and the appropriate solver version and press "OK". 

Note: The template file is stored in the  installed directory C:\Program Files\Madymo\madymo_2406\share\etc "template_restart.xml".

Step3:

The user can specify the time of restart within CONTROL_RESTART. The user can also modify the values of various xml attributes in the restart file by using "Override elements".

Step 4: 

Once the restart model is created, the restart run can be submitted as:

madymo_solver -rst model.rst restart_file.xml

Note: Select the .rst file that is created in the initial run.

Remark:

Appendix H of the reference manual describes the restart topic in general
