I would like to implement a temperature profile as a boundary condition along a wall in a curved channel. The profile should always be normal to the bottom wall and along the right wall. The problem is that i cant use the y coordinate as a reference since the channel is curved.
How can i implement a temperature profile which is depended on the distance from the bottom wall?April 13, 2022 at 2:36 pmSwathi V. V.Ansys EmployeeHello Can you try to apply the thermal boundary condition as an expression w.r.t to the coordinate perpendicular to bottom wall ( the direction along which you need the temperature variation)

April 17, 2022 at 11:51 amNoIdea08SubscriberThank you very much for your help. Unfortunately i still couldn't figure out a way to implement a temperature profile.
@SVV: Yes this is what i need. A cordinate which is perpendicular to the bottom wall. But i still cant figure out how to express this using expressions. I tried to get the distance from a boundary zone but used the wrong syntax --> ElementWallDistance('bottom_wall)
Could you maybe tell which is the correct way to express the distance from a specific boundary zone/ wall?
Thank you very much!
