We report some preliminary results of our ongoing non-perturbative\ncomputation of the twisted 't Hooft running coupling in a particular set-up,\nusing the gradient flow to define the coupling and step scaling techniques to\ncompute it. For the computation we considered a pure gauge SU(3) theory in four\ndimensions, defined on the lattice on an asymmetrical torus endowed with\ntwisted boundary conditions in a single plane, and related the energy scale of\nthe coupling to an effective size combining the size of the torus and the rank\nof the gauge group. Additionally, we explore some of the effects of the\nfreezing of the topology on the computation of the coupling.\n
