Description

The Cuboid Shape component models a generic ideal thermal conductor with cubic shapes.

It could get thermal information from each cubic divided by Nodes.

The geometry of Cuboid Shape is illustrated by the following image.

In the case of Cuboid Shape Nodes is [3, 3, 3] as shown below.

        

The Cuboid Shape has ports: left, right, front, back, top, and bottom. It could get thermal information from each port using probe.

The number of the probe is determined by the priority of L, W, H and direction is right, back, bottom. The following is order when using probe at port_center.

 

The order of the nodes of each surface is the following.

     

Left and right surface nodes as viewed from left 

Front and back surface nodes as viewed from front

Top and bottom surface nodes as viewed from Top

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.

(For more details about the relation between color and temperature, see Color Blend  help).
