I'm working with the Simscape tool and wondering if there is a way to set up a common configuration for different simscape components.

For example, if I have a model with 30 resistors, and I want to set a type of tolerance, and put a tolerance value x on all of them, i'd like to know if it could be done at once and avoid modifing every component one by one.

Thanks!

Hi @Alex,

For changing the 'Tolerance' parameter for all the Resistors in a model, a MATLAB script can be used to iteratively edit the value in one go. See example script below:

% Define your model name
model_name = 'modelName';
% Load the model (if not already open)
load_system(model_name);
% Define the tolerance value you want to set
tolerance_value = 0.15; % 5% tolerance
% Find all resistor blocks in the model
resistor_blocks = find_system(model_name, 'FollowLinks', 'on', 'LookUnderMasks', 'all', 'MaskType', 'Resistor');
% Loop through each resistor block and set the tolerance parameter
for i = 1:length(resistor_blocks)
    set_param(resistor_blocks{i}, 'R_tol', num2str(tolerance_value));
end
% Save the changes to the model (optional)
save_system(model_name);
