Flux in a Define_Profile
 

I assign the same flux in a define profile udf but get opposite directions. I.e flux-in on one wall and the flux-out on another wall. I have to mention the flux is formulated from a vector dot n (the unit normal area) Please advice

udf
 

hi,

can i modelling asphaltene precipitation that exist in crude oil by uusing ceramic filter monolit by defult formolation in fluent?

i want to modelling separation of asphaltene from crude oil by 19-channel ceramic filter,but i think it is not define in FLUENT that precipitate asphaltene on surface of ceramic channel base on diffrences between pore size.

i must write UDF for this porpuse or not?

most of oil flow must pass through the membrane wall and most of asphaltene must form a gel-layer and precipitation on inner surface od channel.

please help me as soon as possible

thank you so much
