ABSTRACT
A
meshfree method namely, element free Gelerkin (EFG) method, is
presented in this paper for the solution of governing equations of 2-D
potential problems. The EFG method is a numerical method which uses
nodal points in order to discretize the computational domain, but where
the use of connectivity is absent. The unknowns in the problems are
approximated by means of connectivity-free technique known as moving
least squares (MLS) approximation. The effect of irregular distribution
of nodal points on the accuracy of the EFG method is the main goal of
this paper as a complement to the precedent researches investigated by
proposing an irregularity index (II) in order to analyze some 2-D
benchmark examples and the results of sensitivity analysis on the
parameters of the method are presented.
