A Posteriori Error Estimators for Adaptive Spectral Element Techniques

  • Catherine Mavriplis
Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NNFM, volume 29)

Summary

Aspects of adaptive spectral element methods are presented with emphasis on the a posteriori error estimators used in the automatic mesh refinement process. The nonconforming formulation of the method is reviewed in an effort to illustrate the various mesh refinement options available. Single mesh a posteriori error estimators are developed for the spectral element method. These estimate the actual error incurred by the discretization on a local per element basis and predict the convergence behaviour of the numerical solution as well. As a result the error estimators serve as criteria in the choice of refinement options. The usefulness of the estimators is demonstrated through examples of Navier-Stokes calculations.
