Expansions and Extrapolation of Stokes Eigenvalue Problems by Bilinear Element with the Stream Function-Vorticity-Pressure Method
摘要
考虑利用Q1元来求解Stokes特征值问题的误差渐进展开式,并以此为基础进行外推获得高精度.
The asymptotic error expansion of the approximation for the Stokes eigenvalue problems by the Q1 mixed finite element with the stream function-vorticity-pressure method is considered. The Richardson extrapolation is adopted to improve the accuracy of the eigenvalue approximation.
