Hello, i am only starting learn ansys fluent and have this 2d task. I have liquid(water) and inside it a circle( i am added it with "Cell Register) with molten fluid(cooper). I need to simulate the heat transfer from this circle to a water with formation of vapor bubbles. I use VOF model with 3 fluids, use energy , use mass transfer from water to vapour ( evaporation-condensation) and patch the region with circle with high temperatue(1000 K) , gravity is off. As a result, bubble and vapor film formation does not occur. Help me pls. Thank you.
In other words, I have 2d plane with water with temperature 300 K and circle region of melt with temperature 1000 K and need to get heat transfer between melt and water with formation of vapour babbles.( so the water must begins to heat up and start evaporate) I patched the circle region with temperature 1000, but no evaporation occurs) What should i do else?

I think that patch the circle region with temperature it is a worth decision because after calculating in CFD post i have similar temperature field in all points after first timestep
zero time step

first time step
