Notes: A methodology is presented for measuring the effectiveness of a finite element approach when compared with a reference finite element approach with respect to accuracy and computation. The effectiveness measure is applied to the Hughes reduction method for structural eigenvalue problems and three proposed analogous methods for fluid or fluid-structure problems. Comparisons of the three methods with consistent interpolation solutions indicate that improved effectiveness can be obtained.
