Finite element methods of least-squares type. (English) Zbl 0914.65108
Both auhors have many significant contributions on “finite element methods of least squares type”. This paper presents a selective account of past and ongoing work of the developments in least squares finite element methods with a strong focus on the advances for the Stokes and Navier-Stokes equations, for convection-diffusion elliptic problems, inviscid, compressibe flows problems and electromagnetic problems.
The presentation includes general formulation, analysis and implementation of such least squares finite element methods for the different types of problems mentioned above. It is completed by a brief review of other related methods (collocation, restricted least squares and least squares/optimization methods). References to 120 papers are included and commented.
This is a very nice and basic paper to anyone interested on this subject.
