WebThe Heat Transport (HEAT) solver is a physics-based simulation tool for solid-state devices. The solver can evaluate the heat transport equation independently, or self-consistently solve the coupled system of equations for heat transport and conductive electrical transport to calculate thermal response to Joule heating in an electrically driven system. In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the rate of transfer of heat of a material from the hot end to the cold end. It has the SI derived unit of m /s. Thermal diffusivity is usually denoted by lowercase alpha (α), but a, h, κ (kappa), K, and D are also used. The formula is:
