A computer simulation of a Cold Isostatic Press (CIP) densified bodies was carried out to estimate the initial relative density and the coordination number which are important factors to elaborate HIP maps. First, the mean coordination number and the packing fraction of CIPped bodies were calculated. Secondly, these values were compared to those of other simulations for unidirectional packing model. Two assumptions were used to simulate CIPped bodies. They were (a) all particles were rigid spheres of the same size, and (b) they were moved initially toward the center to contact three other particles. The results were as follows: (1) The relative density and the mean coordination number of simulated CIPped bodies are 0.56 and 6.5, respectively. The coordination number is higher than the value obtained for an unidirectional packing model. (2) The present model gives a reasonable relative density and coordination number for a CIPped body. (3) The relative density and the mean coordination number of simulated CIPped bodies give good agreement with the initial state used in the HIP maps.
