MATLAB: How to set “Start simulation from steady state” in Solver Configuration block from Simscape programmatically

Best Answer

The block property which needs to be set is 'DoDC'. If the Solver Configuration block is the current block, it works like the following to enable it:

>> set_param(gcb,'DoDC','on')

To disable it, use:

>> set_param(gcb,'DoDC','off')

MATLAB: Does the Simscape fail to solve initial conditions when I enable the ‘Start from steady state’ option in the Solver Configuration block

If you want to set initial condition targets for block variables then you must ensure that the "start from steady state" option is turned off. This is because when "start from steady state" is used, the solver ignores the initial condition targets you set for the variables and tries to find a steady state initial condition solution. In a big nonlinear model, it might not be able to find a steady-state solution. Even if it does, that steady-state solution is simply "a solution" and might not be a solution that you'd expected based on your variable targets (since those targets are ignored).

MATLAB: How to programmatically replace a referenced model with a Subsystem in Simulink

Assuming that you have a 'parent.slx' model which references a model 'child.slx' (whose block name is 'Model' in the parent Simulink model), use either of the following options:

>> open_system('parent');

>> add_block('built-in/Subsystem',['parent/mySub']);

>> load_system('child');

>> Simulink.BlockDiagram.copyContentsToSubsystem('child',['parent/mySub']);

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

>> open_system('parent');

>> load_system('child');

>> convert2subsys('child');

>> add_block('child/Subsystem','parent/mySub');

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

>> close_system('child',0);

where 'convert2subsys' is defined at the following link:
