Hello all. There is a rectangular domain 20x40x12 m with a weak spring of the benzene vapour. The aim is to model the dispersion of benzene at the absolutely calm atmosphere (but with non-zero turbulence). I have tried a huge number of BC but failed with this task, because of the weak air currents that appear near the boundaries and at the corners. Their speed is about some centimeters per second but they are killing the process. Instead of descending to the ground (benzene has the density of 3,14), instead of penetrating through the boundary, instead of leaving the domain the benzene vapour goes up and curl and wirl ans so on. Please share your experience and help with a hint as of how to construct absolutely calm atmosphere. If it would be windy atmosphere or powerful spring of the vapour there would be no problems. Thanks.
