This paper investigates a high-order mixed isogeometric analysis for the Stokes problem with variable viscosity. We proposed and analyzed a new numerical scheme that can be viewed as a generalization of the classical Taylor–Hood elements. The numerical experiments are provided to validate the efficiency of scheme proposed.
