Adaptive meshing for two-dimensional thermoelastic problems using Hermite boundary elements

Space-Time Meshing for Two-Dimensional Moving Boundary Problems

A new meshing strategy for two-dimensional space-time moving boundary methods is presented. The method breaks the space-time domain into time slabs, and tesselates each sequentially. Within each time slab, the mesh is generated by extruding the lower time plane, moving the boundary, adding and removing vertices near the boundary, and smoothing. Unlike other strategies, topological changes to th...

Multigrid Solution Strategies for Adaptive Meshing Problems

This paper discusses the issues which arise when combining multigrid strategies with adaptive meshing techniques for solving steady-state problems on unstructured meshes. A basic strategy is described, and demonstrated by solving several inviscid and viscous ow cases. Potential ine ciencies in this basic strategy are exposed, and various alternate approaches are discussed, some of which are dem...

Adaptive Boundary Elements and Error Estimation for Elastic Problems

In traditional thinking, when the elastic problems are solved, we need to repeatedly plot element grids and analyze computing results according to diverse precision requirement. Against the malpractice exists in the above process, a new method of error estimation was suggested on H-R adaptive boundary element method in this paper. Based on the discrete meshes that are generated for the process ...
