Adaptive Finite Element Methods for Rotary Wing Aerodynamics

摘要

We report on the research activity developed under the present contract in the field of anisotropic mesh adaption and error estimation. With respect to the former problem, we describe a method for the insertion of anisotropic mesh layers in general tetrahedral grids. For a-posteriori error estimation, we describe an implementation of a recovery-based estimator and its extension to anisotropic metric-based adaption strategies. Selected examples illustrate the characteristics of the proposed procedures. We conclude by commenting on the results of the research activity and by discussing possible future work in the same field.
