I am working on a model where I want to use the power added by a flow rate source block (see image) as input for further control in the simulink model.

Now, I know this parameter exists in the flow rate source block, but I see no way of retrieving it other than viewing its values in the Simscape simulation result explorer window. A separate output on the block itself or a variable from the workspace would be ideal.

Thank you for your help!

If it's in the Simscape Results Explorer, you should be able to use a Probe block to make it available during simulation as a Simulink Signal.

Another way to get the power, is to add flowrate sensors before and after the source, and take the difference in the energy flow (PHI). The difference should be the power added. The value should match the values you get from the source block itself.
