An OpenFoam Free VKI Seminar - Introduction to the deformable overset method for the simulation of flexible and moving bodies

We thank you for your interest. The seminar is full. New seminars are planned in 2024. We will inform you as soon as possible.

An OpenFoam Free VKI Seminar - Introduction to the deformable overset method for the simulation of flexible and moving bodies

Ir. Romain Poletti, PhD at the von Karman institute for Fluid Dynamics (VKI)

The event aims to bring together OpenFOAM users as well as those interested in potential applications of the code, both for academic and industrial purposes. The seminar will be held in hybrid mode, and it will be organized in the following way:

15:00 Welcome and roundtable

15.30 Session on “Introduction to the deformable overset method for the simulation of flexible and moving bodies” by Romain Poletti, von Karman Institute

Wind turbine blades, tube bundles in nuclear reactors, bird wings, etc. can all experience large motion along with large deformation. CFD simulations of such applications rely on dynamic grids which must continuously adapt to preserve high-quality cells. The present OpenFOAM session introduces the overset method, the deforming mesh technique and demonstrates how their merging allows to simulate bodies with arbitrarily large motion and deformation. The developments are presented with a step-by-step tutorial on flapping and deforming airfoils in OpenFOAM v2012. The tutorial ends with post-processing tools for analyzing results and a brief introduction to coupling OpenFOAM with an open-source Fluid-Structure interaction solver. All code developments will be released on a GitHub link.

16.30 Small presentation of the von Karman Institute and their main applications of OpenFOAM

 All the material to follow the tutorial will be provided to the participants during the event, and an online platform will be created to share material and create discussions.

The event will be organized four times a year and we would like to invite you to share your applications and implementation.
