i have set the wall boundary condition with heat flux w/m2 and i want to set the initial temperature for the same wall.

in my cooling simulation, the initial temperature of wall will decrease and the wall is depend on the heat flux.

however,for the boundary condition setting for wall, the thermal condition "temperature" is only can be set to constant. when i set it as a constant, my wall bc's just display a constant temperature in the result.

when i set the temperature at the wall in "initialize > compute from > wall".
the result still show the similar temperature for my wall boundary conditions.

Please give me any idea to solve the problem. Thank you

Hi Jane

Did you get any reply for your query on heat flux BC. I am also having the same problem of setting constant flux BC for a wall as well as the wall initial temperature. Since the temperature is set as constant in the BC it is showing constant temperature in the result. If i set it to zero, it is showing zero temp close to the wall. But I would like the wall to change the temperature as per the heat flux condition. If you have solved your case then pl help me out. If somebody have an idea how to overcome this problem pl do guide me. Thanks in advance
