| Abstract: | The element-free method (EFM), based on moving least-squares method, is applied to solve the heat conduction problems. The relevant theories of EFM including the choice of weight functions and the meeting of boundary condition are described to obtain discrete equation of the problems. The several numerical examples by applying EFM-based software indicate mat EFM is a potential method to simplify the post-processing and to obtain accurate predictions of heat conduction problems. |
