Multi Criteria Anisotropic Adaptive Remeshing for Sheet Metal Forming in FORGE

摘要

In this paper we present an innovative automatic adaptive anisotropic remeshing technique that has been introduced in the commercial FEM software FORGE. It enables the full 3D simulation of industrial applications of parts with a high aspect ratio such as sheets. An anisotropic mesh is generated in order to adapt to the part and tools geometries, and in order to minimize interpolation error on the velocity field and/or on any other user defined function (eg. temperature, strain ...). By minimizing the estimated error, the anisotropic adapted meshes provide a highly accurate solution, often better than those obtained on globally-refined isotropic meshes and at a much lower cost due to the small total number of nodes..
