Sample Database: 1D and 2D Modelling

Before you continue, please download the sample database. You can do it through the Home tab or by using the link below: Download sample database - 1D and 2D Modelling

This sample database provides a ready-to-use environment for exploring 1D network and 2D surface modelling in InfoWorks ICM.

It is designed to help you open a preconfigured Model group, understand how model components are structured, and step through common workflows such as design, Simulation, and Results analysis.

You can use this database to:

• explore how 1D and 2D models are organised within a Model group
• run predefined Simulations and inspect Results
• apply Network design to size network elements
• test Scenarios and compare outcomes

Contents of the sample database

The sample database includes:

• a 1D network model with pipes, Nodes, and catchments
• a 2D model with a surface Mesh and floodplain behaviour
• predefined Runs, Rainfall events, and Scenarios
• configuration objects for design, Simulation, and Results analysis

Choose your workflow

Select a model type to explore specific workflows.

Work with the 1D model

Use the 1D network model to explore drainage system behaviour and design workflows.

You can:

• review network structure and object properties
• apply Network design to size pipes
• run Simulations and analyse hydraulic performance

See 1D Sample Model: Workflows and capabilities .

Work with the 2D model

Use the 2D model to explore surface water flow, flooding behaviour, and interaction with the network.

You can:

• review the 2D zone and mesh
• run Simulations for surface flooding
• analyse depth, velocity, and Flood extent

See 2D Sample Model: Workflows and capabilities .

Simulation workflows

Simulations combine a network, input data (such as rainfall), and a run configuration to generate results.

For step-by-step workflows, see:

• Run a Simulation
• View and analyse Results

Work with design and scenarios

The sample database includes configurations for:

Network design

Use design constraints and catalogues to size and adjust network elements.

See Network design.

Scenarios

Create and compare alternative configurations within the same model.

See Scenarios.

1D and 2D interaction

The sample demonstrates how:

• 1D networks simulate flow within pipes and structures
• 2D models simulate surface water movement
• flow can transfer between the network and the surface

This enables integrated analysis of flooding behaviour and system performance across surface and network domains.

After exploring the sample database, you can:

• modify model inputs and rerun simulations
• compare scenarios to evaluate design changes
• refine model parameters for your own projects
