A Front Advancing Adaptive Triangular Mesh Dynamic Generation Algorithm and Its Application in 3D Geological Modeling

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...

A Parallel Delaunay and Advancing Front Mesh Generation Approach

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...

Advancing Front Surface Mesh Generation in Parametric Space Using a Riemannian Surface Definition

A method is presented for meshing 3D CAD surfaces in parametric space using an advancing front approach and a metric map to govern the size and shape of the triangles in the parametric space. The creation of the metric map will be discussed. The advancing front mesher generates triangles based on the metric map, stretching them in order to capture the change in parameterization of the surface. ...

Combining Quadrilateral and Triangular Meshing Using the Advancing Front Approach

A fully automatic mesher has been developed which is capable of generating both quadrilateral and triangular elements in 2-D and on surfaces using the advancing front algorithm. This allows the formation of meshes which range from being all-quad or nearly all-quad down to all-triangular. In mixed-element meshes, the number of tri elements present is dictated by the maximum allowable level of qu...
