By using the linear response theory in the Matsubara formalism, the Hall viscosity of a two-orbital superconductor in the presence of a viscoelastic magnetic field is calculated. For a strontium ruthenate superconductor subjected to an external velocity, our calculations at zero temperature show the existence of a topological phase transition and the change in the van Hove singularities due to the variation of the Fermi surface. The deformed Brillouin zone carries two kinds of momentum fluxes in Sr2RuO4. This modification corresponds to a chiral-nonchiral transition for the edge states.
