Abstract

Summary We present a novel approach to unstructured tetrahedral mesh generation in 3D with minimum geometrical input. The boundary of the domain is identified adaptively with adjustable precision. The grid points of the mesh are distributed by means of an algorithm based on the analogy with a system of electrically charged particles. A-priori local refinements of the mesh are possible. Surface and volume meshes are built using advancing-front-type algorithms. All steps of the algorithm are suitable for efficient parallelisation. An application of the presented approach is shown.
