Be sure that you are not creating an internal Boundary Condition (BC).
The BC needs to be on the boundary/the edge of the domain or attached to a suppressed part, which is essentially the boundary again. Try suppressing whatever you are attaching it to and you should be OK.
In fact, you can suppress all solid parts from the mesh - you can still show them all in the results,
You could also look into running scalars, here you could even see where the CO2 goes vs the clean air passing over the car.
Ok, Thanks
I tried it out, but when I am suppressing the fluid volume at the output of the "bottle" , Sim. CFD will ignore the BC for the main Flow.(?)

Hi Jp,
Without seeing the model this is quite difficult. Is it perhaps because you are now suppressing the entire fluid domain also?
Or maybe because the scale of the results only shows the effect of just one of the inlets?
If you hold 'shift' and float your mouse over a cut-plane that is showing velocity magnitude, do you only have zero velocities?
