Hi, I would like to solve the steady-state incompressible Navier-Stokes equations by a spectral method. When I saw the classic primitive-variable finite element discretization of the time-dependent incompressible N-S, it turned out that the coefficient matrix of the derivatives of the unknowns makes the problem. However, if I solve the time-independent version of N-S, I do not have to bother with decoupling, etc, am I right? My second question: do I have to use lower order approximation for the pressure than for the velocity if I regard the steady-state version? Thank you!
