How to use run-time tunable parameter for Constant Volume Chamber (G)

When you use e.g. a DoubleActing Actuator (IL) in Simulink/SimScape, you can select that the initial position displacement parameter should be run-time tunable from a dropdown menu, instead of compile-time tunable.

How can you make a parameter for the initial pressure of the gas to be run-time tunable for a "Constant Volume Chamber (G)"?

Here the there is no option to change from compile-time to run-time.

Exported c++ code has this value hardcoded according to the current value of the parameter in the Workspace.

I think it's do-able. Try this first: make this InitialPressure a Simulink Parameter in the Model Workspace, instead of MATLAB base workspace variable. Will you see it available in the generated code, instead of hard-coded?

Hi Stian,

I understand you would like to make some of the block parameters run-time tunable. You could refer to the following documentations for the same:

1. https://in.mathworks.com/help/releases/R2021a/sldrt/ug/tune-block-parameters-and-matlab-variables.html
2. https://in.mathworks.com/help/simscape/ug/specify-and-change-a-run-time-configurable-parameter.html

Hope this helps.
