MATLAB: How to create Simscape component out of sub-components

Question

Hello,

I would like to know how to use Simscape components to build larger components.

For example, the documentation for a T-Junction found here:

https://www.mathworks.com/help/physmod/hydro/ref/tjunction.html

Shows that the model is actually 3 Local Resistances being used between in the inlet/outlets. It is as if the T-Junction block is a Mask for the underlying model.

I utilize models like this all the time but it would be more convenient to utilize them in the method being shown here. Is it just simply a Mask on a sub-system?

Any help is appreciated.

Thank you.

Chris,

Yes, you can create a Simscape component which is just built from other Simscape components, this is called a composite component. Look at this example which creates a single Simscape block with the same behavior as the DC motor subsystem in the model ssc_dcmotor: https://www.mathworks.com/help/physmod/simscape/lang/composite-component-dc-motor.html

Of course you also could create a mask over a Simulink subsystem to get a similar "block".
