Description

The Cylindrical Shape B component models a generic ideal thermal conductor with cylindrical shape.

Cylindrical Shape is divided into smaller Cylindrical Sector nodes. The total number of these smaller nodes is determined by the Nodes parameter.

You can get the thermal information from each Cylindrical Sector node.

The geometry of Cylindrical Shape B is the following.

The image below illustrates the case of Cylindrical Shape B having Nodes=[4, 3].

The numbers of the nodes are determined by the order from front to back.

These numbers are only related to the port_outer[i] and port_center[i].

The node and port_front[i] numbers as viewed from front side

The node and port_back[i] numbers as viewed from front side

 

If Equal division = true, Cylindrical Shape is divided into equal central angle Cylindrical Sectors.
If Equal division = false, you can input ratio of central angles of divided sectors as Ratio__angle.
The following examples of Ratio__angle are completely the same.

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).
