The SELECTSeries 5 release of SewerGEMS includes many new features and improvements. This technote explores these new changes.
Support for Newer Platforms and Operating Systems:
The following platforms & operating systems are supported:
Note : To integrate ArcGIS 10.3 with SewerGEMS you need to install patch from ESRI.
Please have a look at this support solution, which explains it.
Taps & Laterals
Bentley SewerGEMS V8i SS5, now support taps and laterals elements. Tap is a type of node that connects the lateral to the conduit.
The primary use of taps & laterals is for road and design engineers and OpenRoads users. This is mainly useful where you need to know the exact location of the tap or lateral to perform the clash detection between different utilities using SUE/SUDA.
It enables the user to add inflows along a conduit or channel without the need to break the link element into multiple elements. There could be a number of lateral connections to a single trunk conduit. They are not supported in the Dynamic Wave solver.
Laterals & taps are handled differently in SWMM solver. Laterals are treated as SWMM Dummy Conduits. The SewerCAD (GVF-Convex) solver does not do any hydraulic calculations in the lateral pipe.
Assign Taps to Links tool
This newly introduced tool allows you to automatically assign the tap nodes to the nearest link i.e. to the conduit. It’s useful when you want to assign the bunch of taps to the nearby links.
Tap Locations in Profile View
With the release of SS5, you can see the tap locations in the profile view.
The location of tap in the profile view will change as you change the connection in the properties of taps (Invert to center or Invert to soffit).
SWMM 5.1 support including seepage
The SWMM solver supports a user-defined infiltration flow (Flow /Additional Infiltration) and other solvers have additional support to allow a few different load types, see "Conduit-Infiltration/Inflow and Seepage" for details.
Seepage is the flow loss from the system; it is the seepage of the conduit (or channel) from its bottom and side walls into conduit's surrounding soil. Only SWMM solver supports the conduit seepage loss calculation among the four solvers. you can specify a seepage loss rate and the solver calculates the seepage loss at each time step using the loss rate and conduit flow area (based on the length and wetted-perimeter).
Ribbon in AutoCAD mode
AutoCAD ribbon view of SewerGEMS tools has been modified now, by having all the tools at one place.
Improvements to GVF Convex logical controls window.
In the GVF-Convex solver, the user can use both logical controls and locally defined on/off controls on the pump's Properties editor. In cases of a conflict between the two types of control, the locally set on/off controls are ignored by the solver and a user notification is generated.
Alternatively, the user can set the Ignore On and off Elevation? , attribute in the Operational section of the pump properties grid to True.
User can see all controls and control sets on one dialogue.
Show terrain model in profile view
If you have set up any terrain model in the SewerGEMS model, then you will be able to view that terrain model in the profile view. Terrain model should be active to use this option.
Elevated pipes in profile
The profile view of a pipe that is above the ground elevation has been improved.
Design engine improvements
On-grade spread check - With this version we have improved the solver’s ability to size On Grade inlet opening in the GVF-Rational Solver. Now inlet design constraints can be defined for both on-grade & in-sag inlets, which was previously available only for in-sag inlets.
Visual changes to flextables
Flextable has been made more user friendly, allowing you select the whole column by right clicking on it, Check boxes are now shadowed. The text in boxes is spaced a little more and is much easier to read.
If you need to copy & paste the data from the flex table, you can do so by right clicking on the column heading>Select Column>Click on the copy button>go to where you want to copy the column and click on the paste button.
Batch Morph
Batch morph tool is available for SewerGEMS as well now, which was available before only for water products. Using this tool you can morph one element type into another of element. Like from manholes to catchbasins, transitions,headwalls etc.
GVF convex solver memory management improvements
GVF-Convex solver is modified in this version SS5 of SewerGEMS to handle the large models without causing the memory issues.
Brentwood industries storage chamber library
New Storage chamber library of Brentwood industries storage has been added to storage chamber library.
H2S calculation improvements
Hydrogen sulfide calculations now include reactions in wet wells, improving the calculations of H2S.
Rational method frequency factor
Frequency factor has been added to the Rational Method. To aid in the pairing of larger storm events with the Rational Method or Modified Rational Method, one option is to utilize the calculation options available for employing Frequency Factors.
With the use of a Frequency Factor term the Rational Method effectively becomes:
Q=C'iA
Q = Rational Flow
C' = Runoff Coefficient (Adjusted)
i = Intensity
A = Drainage Area
C'=CfC
Cf = Frequency Factor corresponding to the storm's Return Period (T)
C = Runoff Coefficient (Unadjusted)
You can enable use of frequency option through calculation option.
Enable GIS style.
GIS style Symbology is now available to control drawing characteristics in element Symbology with Microstation platform as well which was only available for Standalone version.
Meaning if you annotated any element with any field, you will be able to see that value even if you zoom in & out in the GIS style.
MicroDrainage Import
In SewerGEMS SS5, you can import & export the Micro Drainage files directly. When imported, it will open up in a new project. The file types are are .sws, .ews, and .fws.
Bentley Map Data Sources in ModelBuilder
New data source has been added to Modelbuilder, which is available only when you are in Microstation platform ( SewerGEMS integration with Microstation) & Bentley Map Mobile application is active.
Communities search
Information available on Communities about some tools like Modelbuilder, Scenarios, Default Design Constrains can be accessed from the tool itself. Which will open up the topic related information on communities
Please see here for more details about using Communities.
RSS feeds in standalone
Once you have been on the Be Communities website and created an account, you can sign up for RSS Feeds. On the Be Communities website, log in, then scroll down to the bottom and you will see, under Social Media, RSS Feed.
Once you have signed up for the RSS Feed and chosen the subjects for your feed, when in StormCAD, you can go to Help > RSS Feeds to see a list of the wikis and/or forums on your feed. Note: You must have created a new project or have an existing project open in order to do this.
After you select RSS Feed a box will open with your feeds. You can do a search by typing a search term in the search bar, or you can do a filter by clicking on the filter button. If you click on the settings button in the upper right corner, a dialog box will pop up. Here you can select a product's feed.
