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 [s], as the water starts to boil you may want to change that to [s], so that you can better capture the solution and it doesnt diverge.
