MESHFREE – simplifying and accelerating complex fluid mechanics simulations
The MESHFREE software is an innovative simulation tool for fluid and continuum mechanics developed by Fraunhofer ITWM and Fraunhofer SCAI. It is based on a mesh-free approach that allows the modelling and simulation of the most complex physical problems while avoiding work-intensive meshing tasks and computationally expensive re-meshing within simulations. This is of particular relevance for problems involving transient flows with moving geometrical parts, free surfaces, phase boundaries as well as large deformations.
The software is optimised to deliver high performance on parallel computing platforms (both multi-core servers and multi-node/cluster systems): it is fully parallelized and exploits the robust and scalable SAMG solvers.
Specialised pre- and post-processing tools complement the core simulation code; the former includes the ability to import geometry data from CAD tools and graphical user-support for model set-up. Users are provided mechanisms for customising simulations, including customization of the underlying partial differential equations or of the automated model refinement criteria.
Target Users and Applications
MESHFREE can be used for the simulation of compressible and incompressible flows. The range of material models provided make it a multi-purpose tool able to model both Newtonian and non-Newtonian flows and also the behaviour of solid materials (incl. granular material flow).
The general fields of application cover free surface and multiphase problems, fluid-structure interaction, phase transition problems. The specific applications for which MESHFREE has been used successfully include:
- Automotive vehicle wading and water management
- Tank re-fuelling and sloshing
- Mixing applications (including mixing of dough)
- Glass formation
