I want to simulate a PCM (phase change material), I could not find it in the help. Any information is highly appreciated. Thanks you

Irrespective of it's a gap pad / phase change material / Thermal paste, we can only assign thermal conductivity/ resistance or thermal impedance. If any characteristics to be observed, you can do it using any available characteristics curve and final operating temperature..

This formula is true when material is in liquid phase. The reference to access is: Poling, B., The Properties of Gases and Liquids, McGraw-Hill Book Company, New York, USA, 2001
