MCDS (Monte-Carlo direct simulation) has been recognized as the most powerful numerical method for analyzing rarefied gas flows. A new efficient method applicable to three-dimensional rarefied flows with complex geometry is proposed; a complex flow field is divided into a network of arbitrary cells used in FEM (finite-element method). The results show that the computing time for the present method using an arbitrary cell system is, at most, 1.5 times that for the method employing a regular cell system. The latter is not applicable to complex geometries. It is shown that the present method is useful for simulating three-dimensional rarefied flows with complex geometry.
