Hello guys,

i wonder if my code is correct, note that the y/R in the picture is actually x/R in my simulation

#define Tinlet 300 //in kelvin
#define Th 1800 //in kelvin

DEFINE_PROFILE(Temperature_Wall,thread,index)
{
face_t f;
real x[ND_ND];

begin_f_loop(f,thread);
{
F_CENTROID(x,f,thread);
F_PROFILE(f,thread,index) = Tinlet + 0.5*(1+tanh(20*(x[0]/Ra-0.45)))*(Th-Tinlet);
}
end_f_loop(f,thread);
}

Many thanks

You do not have Ra declared in the code. It will give compile time error. You need to declare Ra as a real variable and then assign a value. Rest appears to be alright
