Vaporization problem
 
Hello all,

I want to model a water flow over a flat wall, a portion of this wall is heated at 1600K. So the water close to the heated region is going to vaporize. I am using the free-surface option and the VAPORIZATION module. My initial condition is that I have water(L) in the whole domain. I am interested in the steady state solution. For a 1m plate, at low speed (0.1m/s) I get the result I expect (thin water vapor layer). However when I increase the speed, even though I refine the mesh in the heated region, my solution diverges. This seems to be a simple problem to simulate but I can't get it figure out... Any help would be appreciate. Thank you
