Element Connections and Renumbering

Element Connection and Renumbering are basic features for organizing the model. Element Connection is useful when there is a requirement to edit the flow direction or modify the upstream and downstream chamber of an element. Renumbering is suitable when it is required to renumber the chamber/element IDs. Both are useful during the early stages of constructing a model.

Element Connections

The connections window will be deprecated in a future release, since alternative methods are quicker and easier. Reverse an element (or thermal resistor) direction by selecting it and pressing the space bar; you do not need to enter the connection window. Use the Property Editor to change an element (or thermal resistor) connection. Select the new chamber (or node) from the modeling window view, or you can enter the chamber ID.
Figure 1.


There are two major operations that can be performed:

  1. Reverse Element: Reverse Element changes the direction of the Flow element. Select the entity in the GUI (click the element to reverse the element connection) or provide the element number in the Element Number field. It is not necessary to select the upstream and downstream chambers.
  2. Reconnect Chambers: Reconnect Element modifies the element properties with the new upstream and/or downstream chamber. Provide the element numbers in the Element Number field, as well as the new upstream and downstream chambers.
    • Note: You can reconnect chambers using the GUI.
      1. From the Element Connections window, select Reconnect Chambers.
      2. Select Element Number.
      3. Select Upstream Chamber.
      4. Select Downstream Chamber.

        The elements are reconnected. See the image below for an example.

Renumbering

There are three major operations that can be performed:

  1. Single: Use the Single option to renumber a single Flow Element/Chamber by providing the existing ID number and the new ID number. For example, if the Item Number is 7 and the New Number for the chamber is 8, after clicking Apply, the chamber ID will be changed from 7 to 8.
  2. Resequence: Use Resequence to rearrange the Flow Element/Chamber by providing a Starting ID number. For example, if a model consists of chambers 3, 5, and 20 and you provide the Starting ID number as 10, after clicking Resequence, the new chamber IDs will be 10, 11, and 12.
  3. Offset: Use Offset to rearrange the Flow Element/Chamber by providing the ID offset number. For example, if a model consists of chambers 3, 5, and 20 and you provide the ID offset number as 100, after clicking Offset, the new chamber IDs will be 103, 105, and 120.
