The capacitance C of a node is computed from the thermophysical properties of the subvolume evaluated at temperature T of the node. The transient solution routine does require the thermal mass of the nodes. The computational time step used in the transient solution is driven by small thermal capacitance diffusion nodes which are connected by large thermal conductors. Therefore, arithmetic nodes, when used with discretion, can save considerable computer time. The measure of the ability to carry a heat flow.
Heat flows from a region of higher temperature to a region of lower temperature.
Conduction is the process by which heat flows within a medium or between different mediums in direct contact. The energy is transmitted by molecular communication. Conductors which represent conduction or convection paths are referred to as linear conductors because the heat flow is a function of the temperature difference between nodal temperatures to the first power. The property of a material to conduct heat in the form of thermal energy. Conductors are used to represent heat flow paths from node to node.
