introduce experimental values
 
hi , please i have a question in fluent if you can help me , i have a wall ,where in the outdoor i have temperature change each hour (experimental value ) , and the time step for the simulation must be 0.1 sec (for phase change materials ) , how i can introduce temerarure value , thank's
:confused:

Use the DEFINE_PROFILE macro for creating a boundary condition for your temperature. This temperature profile can be a function of time by using the macro CURRENT_TIME; for example:

Code:
F_PROFILE(f,t,i) = 293.15 + 0.1*CURRENT_TIME;
which corresponds to T(t) = 293.15 + 0.1t.
