Error loading Simulink with Simscape blocks

I have a problem opening Simulink Models that contain Simscape blocks. When I open the model the Matlab Command Window displays:

"Warning: Physical modeling domain definition file input.m not found. You will not be able simulate this model. Please close your model, then add the domain definition file to the MATLAB path and re-open your model.

Warning: Physical modeling domain definition file output.m not found. You will not be able simulate this model. Please close your model, then add the domain definition file to the MATLAB path and re-open your model."

The Simulink Diagnostic Viewer displays for every single Simscape block I used: "['Modell_Kreiselpumpe_Motor_Kreislauf_03032020/Ammonium-Water']: Parameter check for block 'Modell_Kreiselpumpe_Motor_Kreislauf_03032020/Ammonium-Water' failed.

Caused by:

• Too many output arguments.

Component:Simulink | Category:Model error"

I already tried to add the input.m resp. output.m file but I could not find it.

How can I solve this problem?

Hello Joel, thanks for your answer. I already did contact the tech support and was able to solve the problem by installing matlab version r2020a. Everything is working again. Regards, Thilo
