thank you very much. No i am not solving heat transfer. It should simulate the flow of a Polymer resin through glass fibres which are pulled through the die from the left to the right side. What i expect is the resin after entering the porous domain flowing to the right exit.
I tried your advice with a steady simulation, but when i use moving reference frame the liquid is not really flowing to the right side. I attached some picture which i made after 100, 200, 300 and 700 Iterations. It is flowing in both directions. It is supposed to flow just to the right outlet. Did i do anything wrong?
If you have any other Ideas i would be very thankfull.
