In Pipe Flow Expert, you can stop the flow of fluid through any pipe in the system by selecting the Open/Close pipe mode and clicking on a pipe in the Drawing pane to close the pipe. With the Closed Pipe feature, you can evaluate different configuration scenarios within the system when calculating the results. 


To close a pipe in the pipe system:

  1. Click the Open/Close Pipe button, DrawToolButtonOpenClosePipe02.dib, on the tool bar to select open/close pipe mode.


  1. Click any pipe in the Drawing pane which you want to close. The pipe will be closed.


  1. To re-open a pipe, click a closed pipe with the Open/Close cursor. The pipe will be re-opened.
  2. Click the Show Item Info button, DrawToolButtonShowInfo02.dib , or right click to exit the Open/Close pipe direction mode.


A selected pipe can also be opened or closed by using the Pipe Pop-up menu option. A Closed pipe will be displayed ‘grayed out’ and ‘dotted’ on the drawing to indicate that the pipe is no longer part on the functioning system. Note: care must be taken with this feature, as a non-functional system may result from this action and Pipe Flow Expert may not be able analyze the resulting network.
