Hi,
You can copy the contents from one Simulink model to another through appdesigner using subsystem commands. Here is the link you can refer to
Here is the small example to copy contents from one model to a subsystem of other model.
open_system('vdp');
new_system('new_model_with_vdp')
open_system('new_model_with_vdp');
add_block('built-in/Subsystem', 'new_model_with_vdp/vdp_subsystem')
Simulink.BlockDiagram.copyContentsToSubsystem...
('vdp', 'new_model_with_vdp/vdp_subsystem')
Hope this helps!
