assign both heat flux and temperature on wall
 
Is there any strategy to assign both temperature and heat flux on a wall in Fluent? Also by UDF. Please suggest me
Thank you

Your question is interesting.
why both? does it really make sense? i work on a simulation for a heatexchanger(between two fluids) and i take "coupled" and let the value of the heatflux=0.
The Temperature is in the function of heatflux inside(i think):
dot q = dot Q/ A
dot Q = lambda * A * delta T / l

i would like to know your exact problem

I'm solving a problem that involves heat transfer in porous medium.
I'm using two equation for energy. So i have two domains one for fluid phase and another for the solid one. At boundary i have to impose a heat flux for both phase. This is not a problem. But at these boundary fluid and solid temperature have to be the same. So i need to use this "strange" boundary condition.
