We also find that the method can generate unphysical solutions if not used with care, so careful comparison of solutions to experimental or analytical results for each class of problems is necessary. However, for many problems, such as shock waves, better results may be obtained with more traditional finite difference methods. For some problems, it may prove to be the method of choice. The SPH method has received much less development effort than the others, but even in its present form it is a useful tool for getting approximate solutions to a wide variety of three-dimensional fluid dynamics problems at moderate computational cost. Our findings suggest that he SPH methods has great potential for development into an alternative to finite difference and finite element methods.

Accuracy and efficiency are also assessed.

We present a review of the smoothed particle hydrodynamics (SPH) method and present several sample problems to illustrate its properties as a general purpose computational fluid dynamics technique.
