velocity and temperature profile
 
hi..
i am modeling "simulation of so2 dispersion from stack". i use spalart allmaras, energy, and species transport without reaction. i also define velocity and temperature profile in velocity inlet.
After i iterate the case, the result was good (velocity and temperature profile didn't change). But after that i add gravitational acceleration in operating conditions and running it, the result is strange. velocity and temperature profile that i've made was changing.why could this happened???

thanks for helping
