Numerical Investigations on Several Stabilized Finite Element Methods for the Stokes Eigenvalue Problem

الملخص EN

Several stabilized finite element methods for the Stokes eigenvalue problem based on the lowest equal-order finite element pair are numerically investigated.

They are penalty, regular, multiscale enrichment, and local Gauss integration method.

Comparisons between them are carried out, which show that the local Gauss integration method has good stability, efficiency, and accuracy properties, and it is a favorite method among these methods for the Stokes eigenvalue problem.
