Automatic generation of hexahedral and tetrahedral meshes.

In this paper we present in depth one of the preprocessing steps of our software system for the simulation of soft tissue behaviour and biomechanical processes. The entire system can be used by surgeons for preoperative planning and prediction of postoperative results. The software creates a pipeline to automatically construct meshed datasets for finite element modelling from presegmented patie...

Compressing Hexahedral Volume Meshes

Unstructured hexahedral volume meshes are of particular interest for visualization and simulation applications. They allow regular tiling of the three-dimensional space and show good numerical behaviour in finite element computations. Beside such appealing properties, volume meshes take huge amount of space when stored in a raw format. In this paper we present a technique for encoding connectiv...

Fast Ray Traversal of Tetrahedral and Hexahedral Meshes for Direct Volume Rendering

The importance of high-performance rendering of unstructured or curvilinear data sets has increased significantly, mainly due to its use in scientific simulations such as computational fluid dynamics and finite element computations. However, the unstructured nature of these data sets lead to rather slow implementations for ray tracing. The approaches discussed in this paper are fast and scalabl...

Low-order continuous finite element spaces on hybrid non-conforming hexahedral-tetrahedral meshes

This article deals with solving partial differential equations with the finite element method on hybrid non-conforming hexahedral-tetrahedral meshes. By non-conforming, we mean that a quadrangular face of a hexahedron can be connected to two triangular faces of tetrahedra. We introduce a set of low-order continuous (C) finite element spaces defined on these meshes. They are built from standard ...

Tetrahedral and hexahedral invertible finite elements

We review an algorithm for the finite element simulation of elastoplastic solids which is capable of robustly and efficiently handling arbitrarily large deformation. In fact, the model remains valid even when large parts of the mesh are inverted. The algorithm is straightforward to implement and can be used with any material constitutive model, and for both volumetric solids and thin shells suc...
