Meshing Volumes Bounded by Smooth Surfaces
This paper introduces a three-dimensional mesh generation algorithm for domains bounded by smooth surfaces. The algorithm combines a Delaunaybased surface mesher with a Ruppert-like volume mesher, to get a greedy algorithm that samples the interior and the boundary of the domain at once. The algorithm constructs provably-good meshes, it gives control on the size of the mesh elements through a u...
متن کاملSimultaneous Refinement and Coarsening: Adaptive Meshing with Moving Boundaries
In the numerical simulation of the combustion process and microstructural evolution, we need to consider the adaptive meshing problem for a domain with a moving boundary, in which, the submesh in the region behind the moving boundary needs to be coarsened while the submesh in the region ahead of the moving boundary needs to be reened. In this paper, we present a uniied scheme for simultaneously...
متن کاملBalanced restoration of geological volumes with relaxed meshing constraints
Balanced restoration consists in removing the effects of tectonic deformation in order to recover the depositional state of sedimentary layers. Restoration thus helps in the understanding of a geodynamic scenario, reduces structural uncertainties by testing the consistency of the structural model, and, under mechanical behavior assumptions, evaluates retro-deformation. We show how an elastic fi...
متن کاملEnergy-Minimizing Approach to Meshing Curved Wire-Frame Models
In the initial phase of structural part design, wire-frame models are sometimes used to represent the shapes of curved faces. Finite element analysis (FEA) of the curved faces requires that a well-shaped, well-sized mesh be smoothly generated on them. The algorithm described in this paper generates such a mesh from a wireframe model by the following three steps: (1) projection of the vertices o...
متن کاملIdentifying and Meshing Thin Sections of 3-d Curved Domains
Realization of the full benefits of variable p-version finite elements requires the careful construction of prismatic elements in thin sections. This paper presents a procedure to automatically isolate the thin sections using the points on an approximate medial surface computed by an octree-based algorithm. Using the pairs of triangles associated with medial surface (MS) points, in conjunction ...
