Abstract. We have investigated inhomogeneous generalization of Bianchi type VIh string cosmological model for stiff perfect fluid distribution. To obtain the deterministic solution of Einstein's field equations, we assume that the isotropic pressure p is equal to string rest density ρ. Each of the cases 1 + h = 0 and 1 + h ≠ 0 gives rise to families of universe. The model obtained is expanding, shearing and non-rotating universe. Some physical and geometrical features of the model are also discussed.
