Is it possible to set up the Simulation Data Inspector to use the physical units set in Simscape blocks in R2020a?

Right now it is not automatically possible and our development team considers this for a future release.

In the meantime the Simulation Data Inspector API can be used to automate it.

There for see the following example code, where the most recent run gets looped through and all signals with 'Pa' unit and 'm^3/s' unit are automatically changed to 'bar' and 'L/min':

% Get run IDs for most recent run
allIDs = Simulink.sdi.getAllRunIDs;
runID = allIDs(end);

% Get Run object
run = Simulink.sdi.getRun(runID);

% Change property for all signals in the latest run
for i = 1:run.SignalCount

    % Get signal IDs
    sigID = run.getSignalIDByIndex(i);

    if (run.isValidSignalID(sigID))

      % Get signal
      sig = Simulink.sdi.getSignal(sigID);

      % Change signal units
      if strcmp(sig.Units,'Pa')
        sig.convertUnits('bar');
      end

      if strcmp(sig.Units,'m^3/s')
        sig.convertUnits('L/min');
      end
    end
  end
