Variational tetrahedral mesh generation from discrete volume data

Unstructured Tetrahedral Mesh Generation Technology

The whole process of mesh generation is presented in detail. Advancing front technique (AFT) is proposed for 3D tetrahedral mesh generation [1]. AFT starts from initial front. Initial front is a boundary surface conformal triangulation. On each step a new tetrahedron is constructed and the front is updated. At this point local mesh size could be selected automatically in order to create quasi-u...

Multi-phase Volume Segmentation with Tetrahedral Mesh

Data-driven Tetrahedral Mesh Subdivision

Given a tetrahedral mesh immersed in a voxel model, we present a method to refine the mesh to reduce the discrepancy between interpolated values based on either scheme at arbitrary locations. An advantage of the method presented is that it requires few subdivisions and all decisions are made locally at each tetrahedron. We discuss the algorithm’s performance and applications.

Comparing Techniques for Tetrahedral Mesh Generation

The growing importance of subject-specific modeling and simulation in medical applications has increased the need for automatic techniques for creating high-quality meshes directly from medical data. We discuss the main aspects related to volumetric mesh generation from iso-surfaces. We take a practical approach, and the main focus of this paper is evaluating processing pipelines using widely a...

Balanced Octree for Tetrahedral Mesh Generation

Nowadays, with the advances of Finite Element Analysis (FEA) packages, some of the engineering and design problems such as stress or thermal deformation can be successfully solved. These are convenient for better incorporating the design constraints of various tasks such as injection molded parts, or rapid prototyping and tooling. Mesh generation is the major step of finite element method for n...
