We are doing a storm water system modelling. In that from one catchbasin we are going to run two number of pipes and connect it to another catchbasin. As civilstorm performs center to center modelling, is there any other method available to have this modelled.Thank you!
Hello Shobana,
There are two ways to model this situation, if you are modeling your network using Implicit or Explicit (SWMM) the software will do the flow splitting automatically after you add the two pipes to your catchbasin as explained in the following article:
Modeling a flow split (diversion) in SewerGEMS or CivilStorm
If you are using the GVF-Rational solver, you will have to use the "GVF-Rational solver" field on the conduits to be able to model this flow division, as exemplified in the following article:
Modeling a flow split (diversion) with the SewerCAD or StormCAD numerical solver

To add to Luca's response - if you are referring to having two parallel pipes between the catchbasins, you can simply enter "2" for the "number of barrels" field in the properties of a single conduit connecting between the two catchbasins. This simulates two pipes of the same size at the same invert. See: Understanding the impact of multiple barrels for a conduit
If the two pipes leaving the single catchbasin have a different size, slope or invert, you can model them as two separate conduits per Luca's post. Note that you can add bends to the pipe so that both are visible in the drawing pane (to address your point about center-to-center)
