The main characteristic of the foams is the existence of pores in them which are distributed randomly. Because of the importance of these materials in engineering and other applications, there has been given importance to modeling of them. In this article, a new method has presented for modeling of closed-cell foams and a program has written in macro environment of CATIA software in Visual Basic language which made the modeling of metallic foams with controllable pore size and density possible. In continue, the effect of the pore size and the number of the holes on the relative density of the foams has studied. Comparing the properties of the modeled foams using the presented algorithm and real foams has shown a good agreement. The modeled foams have the ability to get into the finite-element software.
