Set to 1m for increased speed, but less accuracy\nThermals: Complexity of the thermal model. Thermals=1 uses a closed-loop thermal network, Thermals=0 uses a static temp defind at the Tj pins or by the global temperature\nBPC: Presence of baseplate capacitance or not. BPC=0 disables baseplate capacitance, BPC=1 enables baseplate capacitance\n \nRead provided documentation for full explanation on how to properly use the models
