If you’re serious about modeling, you’ll need to understand how the engine solves differential equations sooner or later. So the next time the engine does something strange, you’ll know what to look for.
Most people, I believe, are like me in that they cannot derive their intuition from equations; it … Read the rest
If you are new to modeling, very quickly you’ll find the peak flow can be different in your graph and your model results summary. How can that be, which one is correct?
The difference lies in how the peak flow is calculated. The engine keeps track of peak flow for … Read the rest
InfoWorks ICM has its own way of managing the different layers and the styles for the map of the model. It might take new users some time to get familiar with the conventions if coming from a CAD or GIS background.
GeoPlan is the main window showing the model and … Read the rest
InfoWorks is a powerful platform with thousands of functions. Ruby scripting is a great way to automate repeated or tedious modeling tasks.
However, getting started with Ruby scripting can feel quite intimidating.
If your job involves moving a lot of data in and out of ICM on a regular … Read the rest
Screen is modeled using the Kirschmer’s equation in ICM. Refer to this Reference PDF on pg 5 for more information.
As shown above, it is an empirical equation based on the configuration of the screen. Field measured data probably will be needed for more accurate results(refer to this study… Read the rest
InfoWorks ICM Ground Infiltration simulates the complicated long term hydrological cycle of sewer infiltration over seasons. Most modelers with a Civil background are not familiar with these concepts, and here are a few diagrams to give you a fast start.
Ground Infiltration Process Overview
Ground Infiltration Parameter Mapping… Read the rest
When reviewing the simulation results, there are two sections TVD and Maxima.
When developing a model in InfoWorks ICM for a proposed condition, you often need to update ground model to include the proposed pond, roads, and housing units.
For smaller-scale projects, the process involves exporting the ground model as a grid, importing it into Civil3D, implementing the necessary changes, and … Read the rest
Model initialization is a crucial, automated step in model preparation. While it typically operates behind the scenes without user intervention, it can sometimes fail or cause undesirable starting conditions in complex models. Understanding the process and the common workaround techniques can help resolve these issues.
To calculate and visualize parameters that are not reported as an attribute or results field in InfoWorks ICM, you can use SQL expression to create a custom field.
For example, freeboard is measured as the distance from the ground of the manhole to the water level inside. Defined as … Read the rest
