Couple two transient studies: Using transient flow field in transport simulation

$

Dear Comsol users,

it would be very kind if someone could help me (I spent several hours trying to find a solution).
I want to use the results of study 1 (time-dependent flow field) in study 2 (time-dependent transport of diluted species).
Coupling via "Values of Variables not solved for" does not work, in my opinion it's only possible to use specific point in times or a stationary solution. Since my flow field changes in time, this is not an option (if I use "t" as an "interpolated" Time, I get the message " Unknown model parameter").

I don't want to solve flow and transport simultaneously because I want to "play" with the transport. And solving the flow field takes quite a while (>2d), while transport converges quite fast.

I found this topic and Ivar refers to an even older post - but I couldn't find it (i searched quite some time).

Thank you very much!
Florian
