Thermal
The Flotherm library files of the parts have a dense grid to accurately capture the laminar boundary layer for flow over the part
in standard JEDEC environments, as well as the heat spreading in the board under the package. In a real system, however, the
part will require a heat sink to be mounted on it. In this case, the predominant heat flow path will be from the die to the heat
sink. Grid density lower than currently in the package library file will suffice for these simulations. The user will need to
determine the optimal grid for their specific case.
