Real-Time Control (RTC) Rule Editor in InfoSWMM and InfoSWMM SA

Real-Time Control (RTC) Rule Editor in InfoSWMM and InfoSWMM SA

InfoSWMM and InfoSWMM SA offers an advanced RTC rule that could be used to effectively simulate the operation of pumps and flow regulating structures such as weirs, orifices, and outlets. Unlike Simple Controls, RTC rules allow for the creation … Read the rest

Control Rules in SWMM5 and InfoSWMM

Control Rules in SWMM5 and InfoSWMM

Operational control rules determine how pumps and flow regulating structures (i.e., orifice and weir) in the conveyance system will be adjusted over the course of a simulation. InfoSWMM and InfoSWMM SA has the following three control classes.

· Initial Status – The initial status … Read the rest

Inertia of Pumps and Motors from Innovyze H2OCalc – Idea for SWMM6

Inertia of Pumps and Motors

The combined inertia of pumps and motors driving them, including the connecting shafts and couplings, is required for transient analysis associated with the starting and stopping of pumps. The equations provided below are intended to be used as an initial guide to the inertia values … Read the rest

Setting Controls For The Pumps and Orifices for the SWMM5 Engine in InfoSWMM and InfoSWMM SA

Using InfoSWMM H2OMap SWMM InfoSWMM SA , you may control the operational status of pumps and flow regulating structures by specifying their initial status, using the simple control rule, or using the RTC rule … Read the rest

Physical Components (Nodes, Links and Pumps) in #InfoSewer

Physical Components

InfoSewer/Pro conceptualizes a sewer collection network as a collection of links connected together at their endpoints, called nodes. The nodes represent manholes, wet-wells, and outlets while the links represent pipes and pumps. The sewer system can be of any topological configuration and can contain multiple loops and outlets.… Read the rest
