- Abstract:
- This paper presents an improved moving least-square ( IMIS) approximation in which the orthogonal function system with a weight function being used as the basis function. The lMLS approximation has agreater computational efficiency and precision than the existing moving least-squares ( MLS) approximation,and does not lead to an ill-conditioned system of equations. By combining the element-free Galerkin ( EFG )method and the IMLS approximation, an improved element-free Galerkin ( IEFG) method for heat conductionis derived. There are two numerical examples that in rectangular and circular domain solved using the lEFGmethod and that demonstrates the method has a greater computational efficiency and precision, and it is simpleand effective
