This tutorial shows how to use overset mesh techniques with OpenFOAM®. The case study (2D) model the fall of a wedge as in https://www.sciencedirect.com/science/article/abs/pii/S0169598305001036. The movement of the wedge is generated by the 6DOF Module of OpenFOAM® (sixDoFRigidBodyMotion) with one degre of freedom allowed: vertical translation. The mesh overset 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 10 min on 4 cores – iAMD® Ryzen 5 4600h.
OpenFOAM®: Tested on versions 2006+ // 2012+. Warning, 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).
