Geodesic Computation for Adaptive Remeshing
This video presents an application of geodesic computation on 3D meshes to surface remeshing. The farthest point paradigm [1] is a powerful greedy algorithm that allows fast and accurate sampling of the underlying surface. The use of a varying speed function for front propagation enables an adaptive placement of the seed points. The connectivity of the resulting mesh is computed using a geodesi...
متن کاملAdaptive 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...
متن کاملAdaptive Remeshing for Real-Time Mesh Deformation
We present an adaptive isotropic remeshing technique that is fast enough to be used in interactive applications, such as mesh deformation or mesh sculpting. Previous real-time remeshing techniques are either not adaptive, hence requiring too many triangles, or make compromises in terms of triangle quality. High quality adaptive remeshing techniques are too slow for interactive applications. In ...
متن کاملAdaptive Remeshing of Non-Manifold Surfaces
We present a unified approach for consistent remeshing of arbitrary non-manifold triangle meshes with additional user-defined feature lines, which together form a feature skeleton. Our method is based on local operations only and produces meshes of high regularity and triangle quality while preserving the geometry as well as topology of the feature skeleton and the input mesh. ACM Computing Cla...
متن کاملAerodynamic shape optimization using adaptive remeshing
Adaptive mesh refinement is one of the most important tools in Computational Fluid Dynamics (CFD) for solving complex engineering design problems. The paper investigates two practical transonic aerofoil design optimization problems using a genetic algorithm coupled with an Euler aerodynamic analysis tool. The first problem consists in the minimization of transonic drag whereas the second is a r...
