Hello everyone

I'm trying to simulate a multiphase flow between air and water inside a humidifier duct, the inlets and outlets are shown below

That's divergence, so isn't desirable. The problem is typically caused by poor mesh, a poorly defined problem or bad choice of settings/models. Given you have multiphase and (possibly) mass transfer there are several areas that things can go wrong. What models are you using, and have you checked the mesh (not just cell) quality?
