Sažetak
ShallowFoam is a 2D solver under the Open Source CFD framework-OpenFOAM. It solves Shallow Water Equations (SWE). A pseudo-2D mesh is used in OpenFOAM for 2D solvers, which means in the top view the shape of the 2D mesh can be arbitrarily, while in the side view, the vertical direction and all the cells have a constant uniform height. In this way, the bottom elevation information is not stored in the mesh but in the parameter field. How to set up a realistic terrain for shallowFoam cases is therefore an issue to be tackled. In this work, we present a way to create a 2D mesh with the elevation data stored in the parameter field using surface interpolation of real terrain data. The method is validated on the flooding simulation of the Malpasset dam break case, which is a good example of a problem with realistic terrain. © 2018, Danube Adria Association for Automation and Manufacturing, DAAAM.
