In order to access a constant or a variable, it must be active. In the GUI you activate it by checking the activation box in the “tree”. From a script you do the same by using ensight.variables.activate(“Name_of_constant_or_variable”) In the next step, you can then access it with ensight.ensvariable(“Name_of_constant_or_variable”)[0] For transient cases, it’s only necessary to activate the variable once. Then access it from within a loop over all time steps.
