WebThere are a number of ways the user can list the available boundary conditions in OpenFOAM, with the -listScalarBCs and -listVectorBCs utility being the quickest. The boundary conditions for scalar fields and vector fields, respectively, can be listed for a given solver, e.g. simpleFoam, as follows. simpleFoam -listScalarBCs -listVectorBCs WebProperties The nutUSpaldingWallFunction boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, based on velocity, i.e. U for low- and high-Reynolds number turbulence models. Using Spalding's law gives a continuous nut profile to the wall.
