Ansys Fluent-Condensation of Water Vapors, a CFD Tutorial

Only Vapors are patched in a single zone at a temperature of 380K. Both left and right side are assigned a temperature of 273K to condense these vapors back to liquid. And gravity is applied along the negative X-direction. Condensation can be seen during the making of movie and condensate is moving toward negative X-direction. This is because gravity is assigned in that direction.
