A verified Bentley WaterGEMS CONNECT Edition manual is typically found within the software's built-in help files or as a PDF accessible through Bentley's official documentation
Below is a comprehensive guide based on verified instructional steps for getting started, building networks, and running simulations in WaterGEMS. 1. Project Setup and Configuration
Before drawing, ensure your project environment is correctly calibrated to your region's standards. Create New Model : Start the application and select File > New Create New Hydraulic Model from the welcome screen. : Navigate to Tools > More > Options > Units . Most global users select (System International), but US Customary is also available. Project Properties File > Project Properties to label your project and provide engineer details. Coordinate Systems View > Backgrounds
to add georeferenced files (like .DXF or Shapefiles) to ensure your model is built to scale. Niğde Ömer Halisdemir Üniversitesi 2. Building the Network
WaterGEMS allows for both schematic (approximate) and scaled (GPS-based) layouts. Layout Tool tool on the
tab to place elements like Reservoirs, Tanks, Pumps, and Junctions. Pipe Connectivity
: Click on a starting node and then an end node to create a pipe. The software automatically assigns labels (e.g., P-1, J-1). Importing Data (ModelBuilder) : For large existing datasets, use the ModelBuilder tool
to sync external spreadsheets or GIS databases directly into the model. Bentley Systems 3. Data Entry and Property Management bentley watergems manual pdf verified
Each element requires specific physical data to run a hydraulic calculation. Property Editor : Double-click any element to open its Property Editor . Common inputs include for junctions and for pipes. FlexTables
: To edit data in bulk (like changing the material for all pipes at once), use View > FlexTables
. This provides a spreadsheet-like interface for rapid data entry. Pump Curves : For pumps, you must define a Pump Curve (Head vs. Flow) in the Pump Definitions
manager to simulate how the pump performs under different pressures. 4. Running Simulations Steady-State Analysis
: This determines how the system performs at a single point in time, typically at peak demand. Extended Period Simulation (EPS)
: Used to see how the system behaves over 24 hours or more. This requires Demand Patterns
, which apply multipliers to base loads to simulate morning and evening peaks. Validation : Always click Analysis > Validate A verified Bentley WaterGEMS CONNECT Edition manual is
before computing. This checks for "disconnected" nodes or missing data. : Click the (rocket icon) to run the simulation. A Green light
in the Calculation Summary indicates a successful run with no warnings. Bentley Systems 5. Analyzing and Reporting Results Color Coding Element Symbology
manager to color pipes based on velocity or junctions based on pressure, allowing for quick visual identification of problem areas. : Create a longitudinal view of your network via View > Profiles
to see the Hydraulic Grade Line (HGL) relative to ground elevation. Custom Reports Custom Report manager to export results to PDF, Excel, or HTML for professional documentation. Bentley Systems For official training, you can refer to the Bentley Institute Press materials or the Learning Resource Guide for new users. Bentley Systems Pump Station Design Getting Started in Bentley OpenFlows WaterGEMS 2024
The official Bentley WaterGEMS user manual is a comprehensive document—often exceeding 1,000 pages—that provides a detailed look at advanced hydraulic modeling features. You can access a verified "User Guide" PDF directly within your WaterGEMS installation folder. Core Modeling & Simulation Features
Steady-State & Extended Period Simulation (EPS): Performs snapshots of the network or time-varying simulations (e.g., 24-hour cycles) to understand system behavior over time.
Scenario Management: Allows users to manage and compare different "what-if" situations (e.g., fire flow, pipe breaks, future demand) within a single model file. • OpenFlows Webinars The OpenFlows team (Bentley’s water
Automated Fire Flow Analysis: Specifically evaluates the network's ability to provide required fire flow while maintaining minimum pressure requirements.
Water Quality Analysis: Includes specialized tools for tracking constituent concentration, water age, and source tracing to ensure IDSE compliance. Advanced Optimization Tools
Darwin Designer: Uses genetic algorithms to automatically optimize pipe network designs, minimizing costs while meeting pressure and velocity constraints.
Darwin Calibrator: Helps users calibrate hydraulic models by comparing field-observed data (pressures/flows) against model results to find the most accurate roughness and demand values.
Energy Cost Manager: Analyzes energy consumption and costs for pump operations across various pricing scenarios. Model Building & Data Integration WaterGEMS - Bentley Software Documentation
The OpenFlows team (Bentley’s water division) frequently hosts webinars. Attendees receive verified slide decks and example PDFs that mirror manual content.
Many civil engineering departments have educational licenses. Professors often provide students with a verified PDF via a secure university portal.
