✦ Synopsis

A method is presented for connecting dissimilar ÿnite element meshes in two dimensions. The method combines standard master-slave concepts with the uniform strain approach for ÿnite elements. By modifying the deÿnition of the slave boundary, corrections are made to element formulations such that ÿrst-order patch tests are passed. The method can be used to connect meshes which use di erent element types. In addition, master and slave boundaries can be designated independently of relative mesh resolutions. Example problems in two-dimensional linear elasticity are presented.

In this paper, the authors treat the free-surface waves generated by a moving disturbance with a constant speed in water of finite and constant depth. Specifically, the case when the disturbance is moving with the critical speed is investigated. The water is assumed inviscid and its motion irrotatio

We present a scheme for solving two-dimensional, nonlinear reaction-diffusion equations, using a mixed finite-element method. To linearize the mixed-method equations, we use a two grid scheme that relegates all the Newton-like iterations to a grid H much coarser than the original one h , with no lo
