From the automotive sector to production, simulations and digital twins are crucial to many companies. But certain applications pose challenges for conventional software. Highly dynamic processes such as those involved in hydroplaning, Pelton turbines, or machining of metal are often not reproduced satisfactorily. The team headed by Dr. Jörg Kuhnert and his colleague Dr. Isabel Michel at the Fraunhofer Institute for Industrial Mathematics ITWM has devised a solution that closes these gaps: the mesh-free simulation tool MESHFREE.
The software combines the generalized finite difference method (GFDM), which it uses to solve the conservation equations of mass, momentum and energy, with efficient algorithms for solving linear systems of equations — a feature found nowhere else in the world. The cloud of numerical points that is used can adapt flexibly to moving geometries. This eliminates the need for laborious subsequent corrections in the computational mesh.
MESHFREE is an extremely successful response to a number of issues in industry, addressing the urgent need for simulation solutions. Medium-sized and large companies alike are now using the technology for issues that conventional models are unable to address adequately.
The jury highlights “the continuous development of the technology and adaptation to various industrially relevant issues” as “exemplary.”
