A mesh generation procedure to simulate bimaterials

a mesh generation procedure to simulate bimaterials

it is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. in this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. the non-uniform mesh is generated adaptively based on advancing front technique available in abaqus software. implementing severa...

An improved procedure for 2D unstructured Delaunay mesh generation

This paper presents a procedure for the discretization of 2D domains using a Delaunay triangulation. Improvements over existing similar methods are introduced, proposing in particular a multi-constraint insertion algorithm, very effective in the presence of highly irregular domains, and the topological structure used together with its primitives. The method obtained requires limited input and c...

Geometric Approaches to Mesh Generation

We review three approaches to mesh generation that are based on analyzing and accounting for the geometric structure of the domain. In the rst approach, due to Armstrong, the domain is partitioned into subdomains based on the medial-axis transform, a tool for analyzing spatial structures. In the second approach, due to Cox, the design history de nes a geometric structure of the domain. The desi...

Mesh Generation

A mesh is a discretization of a geometric domain into small simple shapes, such as triangles or quadrilaterals in two dimensions and tetrahedra or hexahedra in three. Meshes nd use in many application areas. In geography and cartography, meshes give compact representations of terrain data. In computer graphics, most objects are ultimately reduced to meshes before rendering. Finally, meshes are ...

A GPU implementation of adaptive mesh refinement to simulate tsunamis generated by landslides

A model to simulate the haemodynamic effects of right heart pulsatile flow after modified Fontan procedure.

The effect of pulsatile pulmonary flow after the modified Fontan procedure was examined in a model that simulated the right heart. An inlet overflow tank (preload), axial pulsatile pump, Wind-Kessel model (afterload), and an outlet overflow tank were connected in series. The standard conditions were flow 2.00 l/min with 12 mm Hg preload pressure, 3.0 Wood units resistance, and an outlet overflo...
