imadzg is on a distinguished road

I'm simulating a flow tube with 2 inlets and 1 outlet using simplefoam. I want to be able to see the concentration of inlet1 in respect to inlet 2, so i added a passive scalar transport and in the boundary conditions, i set 0 for inlet 2 and 1 for inlet 1.

everything works fine, but the results are not correct...

Is my approach good? i'm new to openfoam.

and i also have another question concerning the general time of the flow, how can i see, for example, how much time inlet1 needed to reach the outlet? i'm not talking about time steps, like i need the actual time in seconds if this was a real experiment.

Thank you
