چکیده

We present a new remeshing scheme based on the idea of improving mesh quality by a series of local modifications of the mesh geometry and connectivity. Our contribution to the family of local modification techniques is an areabased smoothing technique. Area-based smoothing allows the control of both triangle quality and vertex sampling over the mesh, as a function of some criteria, e.g. the mesh curvature. To perform local modifications of arbitrary genus meshes we use dynamic patch-wise parameterization. The parameterization is constructed and updated onthe-fly as the algorithm progresses with local updates. As a post-processing stage, we introduce a new algorithm to improve the regularity of the mesh connectivity. The algorithm is able to create an unstructured mesh with a very small number of irregular vertices. Our remeshing scheme is robust, runs at interactive speeds and can be applied to arbitrary complex meshes.

Adaptive 3D Remeshing for Metal Forming Simulation

An alternative remeshing methodology for 3D Abaqus explicit analyses which utilizes mesh mapping is presented. Excessive element distortion in 3D large deformation analyses necessitates remeshing, however in Abaqus explicit, the standard 3D remeshing techniques limits the analyst’s choice of element type. The presented technique allows remeshing of 3D perfectly plastic fully integrated higher o...

Direct (Re)Meshing for Efficient Surface Processing

Many geometry processing techniques exploit the connection between shape and connectivity in triangle meshes to enable advanced processing of the data. These techniques face the challenge that triangle meshes, whether generated by a modeling tool or by 3D scanning, typically contain low quality triangles. The process of constructing good meshes out of sub-optimal ones is termed surface remeshin...

In this paper we present a new local remeshing algorithm that is dedicated to the problem of erosion in finite elementmodels whose grid follows themovement of the free surface. Themethod, which we name Surface Lagrangian Remeshing (SLR), is adapted to 2D Lagrangian models which couple surface erosion with deformation of Earth materials. The remeshing procedure preserves nodes defining the surfa...

Surface segmentation for improved CVT remeshing

We present a novel surface mesh segmentation algorithm that, when combined with the Centroidal Voronoi Tessellation (CVT) remeshing method, produces surface meshes that more closely approximate the input surface mesh than when using CVT alone, using both topological and geometric measures of closeness. By segmenting the input surface before CVT remeshing, fewer triangles are required for the re...

Enhanced remeshing from STL files with applications to surface grid generation

In this paper, we present a robust and efficient technique for surface meshing based on Stereolithography (STL) surface definition. Ridges are correctly identified using checks on dihedral angle and comparisons of the ratio of triangle edge lengths. Robust edge swapping, splitting and contraction are performed with stringent element validity checks. The improved remeshing technique is applied d...
