Licence error #52

Closed p-nieke closed 2 years ago

p-nieke commented 2 years ago

Hi,

I have tried to follow the tutorial using the file 'heat_radiation_1d.mph' from the application library (instead of capacitor. The Managing models commands like client.clear() and client.names() worked fine.

As the heat_radiation_1d model doesn't contain any parameters I created one using the GUI to test the Inspecting models commands. However, this lead to some licence error stated below. Could that somehow be connected to opening the model using the GUI? Just wondering as it was not raised before.

Thanks, Philipp

As license errors go, this is between you and Comsol. No, opening the model in the GUI should not have anything to do with it. In fact, that's the expected work flow: Set up the model tree in the GUI, then script simulation runs from Python.

In the linked issue you said you were using Comsol 5.2a, which is usually installed in a folder named COMSOL52a according to the Installation Guide. However, that license file is in a folder named COMSOL52, i.e. the previous version. I would look into that.

Thanks, will look into that!
