A possibility of simulating a perfect fluid using scalar and spinor fields with different nonlinearities is investigated. Exact cosmological solutions to Einstein's equations with the scalar and spinor fields are compared to the corresponding ones with a perfect fluid with a barotropic equation of state. © 2009 Pleiades Publishing, Ltd
