Model coupling with OpenMI – Introduction, basic concepts and live demonstration

OpenMIDid you ever try to couple interacting processes, e.g. surface and subsurface water flow? OpenMI (Open Modelling Interface) is an OGC standard that allows time-dependent models to exchange data at run-time. When the standard is implemented, models can run simultaneously and share information at each time step, making model integration feasible at the operational level.

In this webinar, we will show the possibilities of model coupling with OpenMI to modellers and project managers in water related integrated modelling and other interested attendees.  We will present different research projects and case studies where OpenMI has been applied in the past and illustrate the added value of model coupling. You will also learn how the different processes were coupled. Ideally, you have basic experiences with computer model simulations and are familiar with computational grids, boundary conditions and model forcing.



This webinar covers the following topics:

  • What is OpenMI?
  • Examples of water flow simulation models
  • Coupling mechanisms
  • The OpenMI configuration editor
  • Setting up an OpenMI composition
  • Migrate existing models to OpenMI compliance


The lecture was given by Dr. Bernhard Becker (OpenMI Expert, Deltares) and Andreas Burzel (Flood Risk Analyst, Deltares).
