I currently am having an issue with using SimLab Flux solver. I have attached the error log text file that I received. I cannot provide the model due to IP however I am trying to model a permanent magnet coupling in order to find torque and loss. I have added a motion to the outer part with values shown below. In the error log it says that the AngPos value is not a number. Any thoughts on what could be causing this? Any thoughts greatly appreciated thanks.
