Is there a way to define 2 boundary conditions for one face in FLUENT using a UDF?

Hello, I need to define a heat flux value and a convection coefficient for a wall at the same time...Is there any method to do this because in FLUENT we cannot choose 2 options for wall at the same time..
Danke!

i think you can do that by creating a box around your wall/surface/body at which you want to define heat flux

Now you can fill up the box with DM fill tool and quote it as fluid now with form new part too of DM you should generate a new part and then a conformal mesh will get generate which results in a shadow surface in fluent which are coupled by default these are interface surfaces now you can put the two different condition on the same regime as shadow surface are additional surface only...

Hope this helps I am too a learner
