In this work, we further develop multigoal-oriented a posteriori error estimation for the nonlinear, stationary, incompressible Navier-Stokes equations. It is an extension of our previous work [B. Endtmayer, U. Langer, T. Wick: Two-side a posteriori error estimates for the DWR method, SISC, 2019, accepted]. We now focus on h mesh refinement and p enrichment for the error estimator. These advancements are demonstrated with the help of a numerical example
