AutoPIPE can model a Victaulic fitting using a number of approach mentioned here.
However this is a very difficult and demanding process. Not to mention, that in some case there are converging issues related to multiple Flexible joints on connected piping.
To avoid modeling time and demands, along with converging issues, suggest to create an AutoPIPE Victaulic component.
Contractors are suggesting Vic Style 77N more and more. It would be good to have an industry standard on how these are modeled...or automatically provided by Bentley based by the manufacturer.
If Victaulic flexible couplings are added, is it worth adding the Grinnel flex couplings as well?
