Distributed Thermal Conductor

Multiple Thermal Conductor connecting Cuboid Node and Cuboid Shape with contact area of each node, calculated by their relative positions  Description The Distributed Thermal Conductor component is used for connecting Cuboid (in Nodes) and CuboidShape (in Shapes) components. This component can take account of contact area size between Cuboid and each node of the Shape. Each contact area size is automatically calculated from both cuboid size and center positions of cuboid. (Note: It cannot take account of relative rotation.) When using this component, first, you must input same parameters as Cuboid into Node Property and CuboidShape into Shape Property with center position of cuboid. Then, connect to of Cuboid and to of CuboidShape.     Equations Contact area ratios Ac_Node[i] and Ac_Shape[i] are defined as follows.  Heat conductance $\mathrm{G__off}$ is used for the heat path without heat flow. (For details, see Cuboid, CuboidShape, Thermal Conductor  help).  Variables (For details, see Cuboid, CuboidShape, Thermal Conductor  help). Connections
