Load external file in ssc block Simscape

I build a "liquid valve" component (.ssc file) in Simscape which includes a dropdown menu to select different valve types. The parameters for each valve are stored as a structure in a separated .m file. Depending on which valve is selected, I would like to "load" the corresponding values into my "liquid valve" component (.ssc file). Similar to the "Thermal Liquid Properties (TL)" component which loads an external file depending on the selected fluid.
How do I "load/import" my external .m file (structure) into my simscape component?

My initial thoughts are to put a mask on the Simscape component(s), and use set_params to pull the values from the data source into the mask.

Hi moritz
As per my understanding, you would like to “load” the corresponding values into the “liquid valve” component depending upon the valve selected.
For this, the simscape component should be modified as follows
parameters
% Define the parameters with initial values and units
param1={0, 'unit'}; %unit should be replaced with the actual units of param1
param2 = {0, 'unit'};
% Add more parameters as needed
end
function setup
% Loading the parameters from the external .m file
% Ensure the .m file is on the MATLAB path
params = feval('valveParams', valveType);
% valveParams is the separated .m file which contains a function that returns the structure of parameters based on the valve type.
% valveType is the type of the valve selected from the dropdown.
% Assign the loaded parameters to the component parameters
param1 = params.param1;
param2 = params.param2;
% Assign more parameters as needed
end
By following this method, parameters can be loaded dynamically to the simscape component based on the selected valve type.
For more information regarding the “feval” function kindly refer the following documentation https://www.mathworks.com/help/matlab/ref/feval.html
I hope this helps.
