Instructs the software to combine rigids that connect to each other into a single element.
This indicates whether these items should be condensed/merged into adjacent elements. For example, a valve with adjacent gaskets and flanges would be combined into a single rigid element.
If activated, then elements are condensed/merged unless there is a valid reason not to (change of cross section, change of operating conditions, restraint at the location, and so forth).
The default value is TRUE.
