You can choose output variables using regex.

Either use for example:

simulate(ModelName,variableFilter="^torque.tau|torque.useSupport$");

Or use the output tab to select output variables in OMEdit.

Hello,
sorry to revive the topic, but I do not understand what to put between "" after variableFilter. I tried putting the variable names but whatever I put modelica creates an output file with only some variables, but not the ones that I want.
In your example torque.tau is the variables named tau in a component named torque ?

The single variable named tau. Anyway, it's a regular expression so you can use things like ".*"
