Hello Rob,

i have two questions : is it possible to define a profile of pressure or temperature at the interior of a  fluid domain, if yes how can i do that? i defined profile for velocity and other quantities using udfs but i would like that the air pressure and temperature variate as function of altitude at the interior of domain

i tried setting 3D Fan zone in one of the fuid zones ( i set the fan origin coordinates at the center of exhaust, i set the fan axis parallel to the flow,the fan velocity and the pressure jump) when i press calculate, the fluent cell returns error folating point and immediately closes) what is the default geometry of the fan and how can i fix this problem?

i appreciate you helping me with this. thank you in advance.  Â
