Dear fluent users
I am trying to simulate an horizontal water-soil geothermal heat exchanger for my master thesis.My problem is i have a function describe variation of ground temperature with depth f(y,t)=........that i have to program it in Fluent .My geometry is too simple :a rectangle as a domain ( y axis the direction of temperature variation) inside it a circle as the wall of the buried pipe(heat exchanger)
please how could i do this
