AbstractWave propagation in unbounded domains has attracted a lot of attentions in engineeringfield Surface waves in off shore structures or dams radio waves or elastic waves causedby blasts are just some examples of applications of which the latter is focused by structuralengineers Several attempts have been made to solve this problem Here some of the solution methodsare briefly reviewed and one of them which is based on finite element method FEM isdiscussed It seems that one of the error sources in this method is the shape andarrangement of the elements To avoid this error we studied meshless techniques such asfinite difference method FDM and finite point method FPM and results of this newmeshless method have been compared with the original method It has been observed that FDM can only solve scalar wave problem On the other hand FPM is capable of solving both types of wave problems while the results are still affectedby pollution error as in the original method using FEM
