✦ Synopsis

A new patch test is proposed for laminated finite elements. Two single-element tests are presented which establish the necessary conditions for convergence of incompatible laminated elements. These conditions are applied to a family of incompatible laminated elements recently developed by the authors. A method for applying these conditions to establish a general isoparametric formulation is given. Numerical results from several multielement patch tests performed on these elements are discussed. Additional numerical examples that support the findings of these patch tests are also presented. 1997

## Abstract Based on finite element formulations for the strain gradient theory of microstructures, a convergence criterion for the __C__^0–1^ patch test is introduced, and a new approach to devise strain gradient finite elements that can pass the __C__^0–1^ patch test is proposed.

The application of the finite-element method to the simulation of meteorological fluid flow problems is reviewed. Early studies were aimed primarily at demonstrating the viability of the method for oneand two-dimensional flows, whereas more recent studies have been aimed at demonstrating the efficie
