This tutorial shows how to use overset mesh capabilities of OpenFOAM®. The case study (2D) is plate oscillating in a tank with a free surface flow. The overset mesh technique is used to capture solid body movements and is particularly interesting for large displacements, where mesh deformation methods fail.
- The tutorial uses the overInterDyMFoam solver (interFoam version with the mesh overset technique) introduced since the 1706+ version of OpenFOAM®.
- Around 20 min on 4 cores – i7-4700MQ CPU @ 2.40GHz.
OpenFOAM®: Tested on versions 1706+ // 1806+ // 1812+ // 1906+. Attention, the tutorial does not work with versions (4.0, 5.0, 6.0, 7.0 etc.) from the OpenFOAM® Foundation (www.openfoam.org).
- The tutorial is designed to run on 4 cores but can be easily modified to be run on the number of core chosen by the user.
It is recommended that you use the latest version of OpenFOAM® + to improve the performance of the overset module.
- Paraview (post-processing).
