Ansys Fluent: Boiling Water

This video shows a 2D simulation consisting on a mass of water boiling on a hot surface. In the video you can see that i use a time dependent expression for the temperature of the hot wall, i do this so at the first time step cause if i dont the solution would have an enormous temperature gradient at the bottom wall and it could cause convergence problems. The other thing is that i start the solution with a time step of 0. 001s, as the water starts to boil you may want to change that to 0. 0001s, so that you can better capture the solution and it doesnt diverge.
