Adaptive Parallel Meshes with Complex Geometry
نویسنده
چکیده
We discuss the automatic creation and adaptive refinement of an unstructured mesh within a complex geometry such as the space surrounding an airplane. This may be formulated as two distinct parts; a non-parallel part requiring global knowledge which automatically creates a coarse compatible mesh, and a parallel local refinement algorithm, which refines the mesh until simulation can begin, then adaptively refines it according to the progress of the simulation. Background-mesh methods, sequential and parallel, offer some promise if good numerical algorithms are available. Sequential advancing front methods combined with the parallel Rivara refinement algorithm are a good choice.

Meshes of high quality are an important ingredient for many applications in scientific computing. An accurate discretization of the problem geometry with elements of good aspect ratio is required by many numerical methods. In the finite element method, for example, interpolation error is related to the largest element angle in the mesh [1]. There is a critical need for algorithms that can gener...
