Hello again everybody,

I'm currently developing a UDF containing a DEFINE_PROFILE macro. Within that I want to set the mass flow of a mass-inlet boundary condition dependent to the current time of a transient simulation.

The problem is, that for my simulation the macro/UDF does not seem to be executed every timestep. Take the following UDF as an example. When I compile & hook this UDF to my mass flow within the boundary condition and then run the simulation, the test message is never shown in the console. It is only shown once after loading the udf (and I think there the value is set once to 0.3). But afterwards the UDF does not seem to be executed again (if I bring in the time dependence with CURRENT_TIME the changes are thus not applied to the actual inlet value)

DEFINE_PROFILE(massinlet_profile, t, i)
{
    Message("TEST MESSAGE TEST MESSAGE \n");
    face_t f;
    begin_f_loop(f, t)
    {
        F_PROFILE(f, t, i) = 0.3;
    }
    end_f_loop(f, t)
}

Thanks in advance, I hope that andybody has an idea what is going wrong here!

DEFINE_PROFILE(massinlet_profile, t, i)
{
   
    face_t f;
 Message("TEST MESSAGE TEST MESSAGE \n");
    begin_f_loop(f, t)
    {
        F_PROFILE(f, t, i) = 0.3;
    }
    end_f_loop(f, t)
}

best regards
