It is the collisionless nature of dark matter, inducing velocity dispersion and shell crossing, which is at the origin of cosmological vorticity generation. In this paper we investigate the generation of vorticity during the formation of cosmological large scale structure using the public relativistic N-body code $\\textit{gevolution}$. We test several methods to compute the vorticity power spectrum and we study its convergence with respect to the mass and grid resolution of our simulations.
