Coupling OpenFOAM and MBDyn with preCICE coupling tool

Abstract

In this work, we show how to couple OpenFOAM (foam-extend) and MBDyn softwares withpreCICE coupling tool to form a strongly coupled fluid-structure interaction (FSI) frameworkfor membrane structures. We use an already existing preCICE adapter for foam-extend and wedevelop an adapter for MBDyn in this work. The coupled FSI framework is verified by carryingout a simulation on a modified cavity test case which has a flexible membrane at the bottom of thedomain. The results are compared with the results of other authors. The solvers and the couplingtool are introduced here briefly.
