Quick start
You do not need an account to follow this. Open app.geonodal.com and you are in.
1. Open a sample network
Section titled “1. Open a sample network”From the welcome screen choose a bundled example network. It loads directly into the map — nothing is uploaded, because the model is parsed and stored locally in your browser.
2. Look around
Section titled “2. Look around”- The map shows the network geometry.
- The layer tree on the left lists model components (junctions, pipes, and so on) as separate, styleable layers.
- Selecting an element opens its attributes.
3. Run it
Section titled “3. Run it”Run the simulation. The EPA solver is compiled to WebAssembly and executes on your own machine, so the result appears without a round trip to a server.
When it finishes, results are attached to the model and become available to style by, query, and chart.
4. Query the results
Section titled “4. Query the results”Model attributes and simulation results are both queryable with SQL. This is the fastest way to answer questions the UI does not have a button for — for example, listing every junction whose pressure fell below a threshold at any timestep.
Where your data lives
Section titled “Where your data lives”Models are stored in your browser’s own storage on your disk. Clearing site data for this origin deletes them, so export anything you want to keep.
