stormcad

Hi,

when i am computing my network there is a error "there are loops in your network and it cannot be modeled except by providing diversions". how can i remove this error? i have provided diversion link but the system does not calculate the discharge coming at that particular node automatically, so do i need to input it in the stormcad after doing the calculation in excel?

Secondly, when i am changing the section size of my open channel network, the invert elevations are not changing automatically, which i suppose is the difference between the ground elevation and depth. Should the invert elevations change automatically? why is it not working in my case?

thanks.

  • Hello,

    Secondly, when i am changing the section size of my open channel network, the invert elevations are not changing automatically, which i suppose is the difference between the ground elevation and depth. Should the invert elevations change automatically? why is it not working in my case?

    More information on how you are modeling the channel may be needed. If you are modeling the channel using the conduit element and setting the conduit type to "Irregular Channel" or similar and manually changing the section size of the link? If so, the invert elevation will not change automatically. The program will assume that the invert elevations remain and the crown will change. You can manually change the invert in the conduit or channel properties or, if you have the property fields "Set Invert to Start?" and "Set Invert to Stop?" to True, change the invert in the nodes attached to the link.

    If you are using StormCAD's automated design, you can also have the program adjust invert elevations. In addition, in the Default Design Constraints (found in the Components pulldown menu), you can define if the inverts or crowns will match in the system during the design process. More information on the automated design function can be found in the Help documentation.

    If you are using the cross section elements with the channel link, you should be able to define the invert elevation in the cross section element, which is how the upstream and downstream ends of a channel are defined.

    If this doesn't help, I may need more information on how the elements are represented may be needed.

  • Also, regarding automated design with open channels, please see Mark Pachlhofer's reply to you in an earlier thread:

    Automated conduit sizing only relates to closed conduits such as circular and elliptical pipes and box conduits, not open channels.
