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 Cuboid Shape (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 Cuboid Shape into Shape Property with center position of cuboid.
Then, connect port_node to port_center of Cuboid and port_shapei to port_centeri of Cuboid Shape.
Equations
Contact area ratios Ac_Node[i] and Ac_Shape[i] are defined as follows.
Ac_Nodei=AciA_Node Ac_Shapei=AciA_Shape
Ac_Nodei=AciA_Node=1 Ac_Shapei=AciA_Shape=A_NodeA_Shape
Heat conductance G__off is used for the heat path without heat flow.
(For details, see Cuboid, Cuboid Shape, Thermal Conductor help).
