Filling Sharp Features on Corner of Triangular Mesh by using Enhanced Advancing Front Mesh (EAFM) method

Parallel unstructured mesh generation by an advancing front method

Mesh generation is a critical step in high fidelity computational simulations. High quality and high density meshes are required to accurately capture the complex physical phenomena. A parallel framework has been developed to generate large-scale meshes in a short period of time. A coarse volume mesh is generated first to provide the basis of block interfaces and partitioned into a number of su...

Filling Triangular Mesh Model with All-Hex Mesh by Volume Subdivision Fitting

The hexahedral mesh (hex mesh) is preferred to the tetrahedral mesh (tet mesh) in finite element methods for numerical simulation. However, generating a hex mesh with desirable qualities often requires significant geometric decomposition and considerable user interactions. Therefore, this process may require days or even weeks in the case of complex shapes. In this paper, we develop a method ba...

Reliable Isotropic Tetrahedral Mesh Generation Based on an Advancing Front Method

In this paper, we propose a robust isotropic tetrahedral mesh generation method. An advancing front method is employed to control local mesh density and to easily preserve the original connectivity of boundary surfaces. Tetrahedra are created by each layer. Instead of preparing a background mesh for mesh spacing control, this information is estimated at the beginning of each layer at each node ...

Snow Globe: An Advancing-Front 3D Delaunay Mesh Refinement Algorithm

One of the objectives of a Delaunay mesh refinement algorithm is to produce meshes with tetrahedral elements having a bounded aspect ratio, which is the ratio between the radius of the circumscribing and inscribing spheres. The refinement is carried out by inserting additional Steiner vertices inside the circumsphere of a poor-quality tetrahedron (to remove the tetrahedron) at a sufficient dist...
