abstract
In this paper, we address the cost versus accuracy capabilities for the generalized FEM (GFEM) which was developed in (Comput. Methods Appl. Mech. Eng. 2003; 192:3109-3161, Int. J. Numer. Meth. Engng 2004; 60:1639-1672, Ph.D. Thesis, Texas A&M University, College Station, TX, August 2003 (Advisor: T. Strouboulis)), and also the construction of two-sided a posteriori error estimates, which can be used to assess the achieved accuracy at all levels of the method.
