Antisymmetric tensor fields arise naturally in superstring theory as well as in some theories with broken Lorentz invariance. However, models containing antisymmetric tensor fields often include anisotropic pressure. I will present a general prescription for constructing ansäzte for antisymmetric tensor fields for use in cosmology. With a series of coordinate-dependent constraints I will show that these models can fit Friedmann-type geometry.
