Hexahedral Meshing of complex and invalid CAD Geometries
نویسندگان
چکیده
The primary requirement for a mesh generator used in an automated tool is robustness. Surface based meshing algorithms fail very often especially with invalid boundary representation geometries. With generic boundary representation formats like STEP or IGES, invalid geometries are very common due to the loss of information and precision in CAD Data Exchange. This paper presents an approach to a robust hexahedral mesh generator that is insensitive to invalid geometries and produces meshes which can be used for stiffness calculations.

Automatic decomposition of complex thin walled CAD models for hexahedral dominant meshing
This paper describes an automatic method for identifying thin-sheet regions (regions with large lateral dimensions relative to the thickness) for complex thin walled components, with a view to using this information to guide the hex meshing process. This fully automated method has been implemented in a commercial CAD system (Siemens NX) and is based on the interrogation and manipulation of face...
متن کاملMeshing Complexity of Single Part CAD Models
This paper proposes a method for predicting the complexity of meshing Computer Aided Design (CAD) geometries with unstructured, hexahedral, finite elements. Meshing complexity refers to the relative level of effort required to generate a valid finite element mesh on a given CAD geometry. A function is proposed to approximate the meshing complexity for single part CAD models. The function is dep...
متن کاملThe Cooper Tool
Abstract. The cooper tool is a new approach to automation of hexahedral meshing (or a wedge/ hexahedral element mix if desired) for a general subset of geometries. The tool recognizes applicable geometries and decomposes such into logically single axis swept subvolumes (barrels) with barrel caps bounding the decomposed pieces. It then enforces strict compatibility constraints by imprinting, int...
متن کاملAdvances in Octree-Based All-Hexahedral Mesh Generation: Handling Sharp Features
Even though many methods have been suggested to meet the challenge of all-hexahedral meshing, octree-based methods remain the most efficient from an engineering point of view. As of today, its robustness, speed and robustness are still unmatched. This paper presents advances made in the Hexotic project, especially in terms of sharp angles meshing, non-manifold geometries and adaptation.
متن کاملAutomatic swept volume decomposition based on sweep directions extraction for hexahedral meshing
Automatic and high quality hexahedral meshing of complex solid models is still a challenging task. To guarantee the quality of the generated mesh, current commercial software normally requires users to manually decompose a complex solid model into a set of simple geometry like swept volume whose high quality hexahedral mesh can be easily generated. The manual decomposition is a time-consuming p...
