3D level set methods for evolving fronts on tetrahedral meshes with adaptive mesh refinement

Conformal Hexaedral Meshes and Adaptive Mesh Refinement

During a numeric simulation based on the finite element method, the h-refinement of the mesh consists in splitting the elements where an error indicator is higher than a threshold. One major point is that the final mesh must be conformal. When the mesh is defined only by triangles or tetrahedra, the junction between two zones with a different level of refinement has been solved for many years. ...

Computational aspects of the refinement of 3D tetrahedral meshes

The refinement of tetrahedral meshes is a significant task in many numerical and discretizations methods. The computational aspects for implementing refinement of meshes with complex geometry need to be carefully considered in order to have real-time and optimal results. In this paper we study some computational aspects of a class of tetrahedral refinement algorithms. For local adaptive refinem...

Parallel Refinement and Coarsening of Tetrahedral Meshes

This paper presents a parallel adaptation procedure (coarsening and re nement) for tetrahedral meshes in a distributed environment. Coarsening relies upon an edge collapsing tool. Re nement uses edge-based subdivision templates. Mesh optimization maintains the quality of the adapted meshes. Focus is given to the parallelization of the various components. Scalability requires repartitioning of t...
