I am trying to solve the problem of convergent-divergent nozzle with pressure at inlet and outlet. Does anyone have the idea how to setup the pressure inlet and pressure outlet boundary conditions in compressible Navier-Stokes solver. Also, give an idea of how-to setup the symmetry bc about x-axis. The input file is also attached herein for reference. Many thanks in advance Wasim Sarwar UPC, Barcelona
