The software itself includes a PDF manual specifically for quick start lessons to help new users understand the tools. You can typically find these under File > Help > Quick Start Lessons .
Quickly decipher validation errors and connectivity issues. Where to Find the Best WaterGEMS Manual PDFs
What specific or module (e.g., pump calibration, fire flow) are you trying to master? Do you have an active Bentley SELECT or LEARN subscription ?
Bookmark the "Fire Flow" chapter. The manual provides the NFPA formulas embedded in WaterGEMS. Use the PDF to verify your residual pressure constraints (typically 20 psi or 138 kPa).
: The size of your model has a direct impact on how long simulations take. The more hydraulic elements (pipes, pumps, tanks) you have, the larger the solution matrix, and the longer it takes to compute. For time-sensitive analyses, consider reducing the model's complexity where possible.
