Use the Update Model Parameters from File step in a stimulus profile to call text files. This step has similar functionality to the VeriStand Editor Model Parameter Manager tab and the Model Parameter Manager Workspace tool. The step can update the parameters of a deployed and running model.
Using the step removes the manual process of launching the tool, updating values, and applying those values. Also, because Update Model Parameters from File is a step, it executes inline with the rest of your stimulus profile code. This ensures that you can update your model at known points within the execution of the stimulus profile.
