Cuboid

A node of Cuboid

 Description The Cuboid component models a generic ideal thermal conductor with cubic geometry. The following image uses Thermal Conductor components  to illustrate the behavior of Cuboid component. Each Thermal Conductor component is connected to the and$\mathrm{port_bottom}.$  All Thermal Conductors are connected to the Heat Capacitor. The  is directly connected to the Heat Capacitor. The geometry of Cuboid is the following.

Equations

(For details, see Thermal Conductor  and Heat Capacitor help).

The geometries of Heat Capacitor and each Thermal Conductor are defined by the following equations.

 Heat Capacitor The volume $V$ is defined by the following equation. $V\mathit{=}L\mathit{\cdot }W\mathit{\cdot }H$
 Thermal Conductor The area $A$ and distance are defined by the following equations. Left and right Thermal Conductors $W\cdot H$$\frac{L}{2}$ Front and back Thermal Conductors $L\cdot H$$\frac{W}{2}$ Top and bottom Thermal Conductors $L\cdot W$$\frac{H}{2}$ If  is true, Left and right Thermal Conductors $W\cdot H\cdot \mathrm{k__cc}\left[1\right]$$\frac{L}{2}$ Front and back Thermal Conductors $L\cdot H\cdot \mathrm{k__cc}\left[2\right]$$\frac{W}{2}$ Top and bottom Thermal Conductors $L\cdot W\cdot \mathrm{k__cc}\left[3\right]$$\frac{H}{2}$ (is completely the same as  is false)

Parameters for Visualization (Optional)

Note: If you enable Show Visualization option, you can visualize temperature change as colored geometry in 3-D Playback Window. To make this function available, you have to enable 3-D Animation option in Multibody Settings.
The quality of the visualization is affected if any open plot windows are behind the 3-D Playback Window. If you are experiencing playback issues, try moving the 3-D Playback Window so that it does not overlap a plot window. Alternatively, minimize or close any open plot windows.
