i am working on 2d-compressible navier stokes equations using finite volume cell-centred frame work...while implimenting the pressure condition at the wall i.e.,dp/dn=viscous terms ,can i store the values of stressess at the nodes so that i can extrapolate these to quadrature points inorder to satisfy the above condition at the wall...or is there any simple approach to satisfy that condition b'cze if i store them i require more memory for that.can anyone suggest me some approach for this???
