I'm trying to setup a 2D nozzle simulation exhausting over a coanda surface into a farfield, using the rhoSimpleFoam solver (laminar, standard day air). I can get the simulation to run, but it will diverge after a few iterations and return a floating point error. My mesh isn't perfect, but it does pass all the default mesh checks. I've set the pressure boundary conditions as totalPressure at the inlet and fixedValue at the outlet, and set the velocity BCs as zeroGradient. Temperature is fixedValue at the inlet and zeroGradient at the outlet. I was wondering if anybody had any idea what I've done wrong?
