Thankyou so much. I understand.Â
I have just checked my timestep size as per formula dt < minimum cell size/velocity and I got around 0.05s.Â
Till now, i was using 1e-5 timestep size so after this calculation, i just reduce the timestep size to 1e-4 to check what will happen and suddenly, the properties starts to change like now volume fraction of liquid increases, temperature in the domian decreases etc. below is the overview of some reports of my calculations.Â
Is it a positive sign that by decreasing, i face no divergence and due to increase of speed of calculation, i saw some improvement in VF? also, should i reduce it further to 1e-3 ?
why still no liquid is coming at the outlet? i checked the vectors (using CFD post) and found that there is some liquid at the wall only. also the temperature at the outlet starts to increase with change of timestep size. does it mean, i am facing some evaporation which is why there is no liquid at outlet ?
