Abstract

Automatic surface meshers have been designed with the intent to eliminate the manual effort involved in creating a finite element model. Naturally, the quality of the mesh must be such that the solver will yield accurate results. For geometries having boundaries with short edges relative to the rest of the geometry, the existing meshers yield poor quality meshes. Hence, the stress analyst must manually attain reasonable mesh quality. This manual effort is very tedious and time consuming. Mesh quality improvement techniques such as smoothing, fail to improve the mesh quality. In this work, a new technique is introduced, which improves the initial boundary node loop quality, and in turn yields high quality meshes. Examples show marked improvement in quality, and the meshes are comprised of fewer elements.
