In general, most mistakes in heat transfer problems are related to the improper or inconsistent use of units when defining material properties, constraints or loads. Pro/MECHANICA makes this issue even more confusing by defining units in a Force system rather than the more conventional Power or Energy system found in most engineering texts. The following table shows the equivalent conventional units system for various Pro/MECHANICA units systems. As can be seen you need to be very careful using the IPS system.
