I am trying to do the thermal simulation of a motor drive where I am using Infineon make FF6MR12KM1BOSA1 as the device to realize a 3 phase inverter. I got the model file (.xml) from Infineon simulation support and I am using that file as the device thermal library file in PLECS. As mentioned in PLECS thermal tutorials, I gave the path for the .xml file in File--> PLECS Preferences. I am using the same folder for .xml file and design. plecs file. When I tried to locate the file in the thermal description window, I couldn't find the library file. In fact that library file fetching option itself is getting disabled. I am using Plecs 3.6 licensed version .Kindly support me to come out of this issue.
NB. Pls find attached the screenshot of the window which creates the issue.
