The meshless local Petrov-Galerkin (MLPG) method in conjunction with the modified precise time step integration method in the time domain is proposed for transient heat conduction analysis in this paper. The MLPG method is often referred to as a truly meshless method because it requires no elements

## Abstract To damp out spurious highβfrequency responses, timeβstep integration algorithms for structural dynamic analysis should have controllable numerical dissipation in the highβfrequency regime. The algorithms should also be unconditionally stable so that the timeβstep size is governed by the
In this paper, a precise time-step integration method for dynamic problems is presented. The second-order differential equations for dynamic problems are manipulated directly. A general damping matrix is considered. The transient responses are expressed in terms of the steady-state responses, the gi
