Vladimir Fuka Guest Posts: n/a	Hello! I use fractional step method with pseudopressure. I set dPhi/dn at inlet and outlet, but should I use periodic conditions for presure on boundaries with periodic conditions for velocity or also use Neumann condition? I am at an early stage of developing and I'm getting span wise pressure gradient which is colliding with periodic BC, is it a bug? Vladimir Fuka
