So the main trick was to add the k-epsilon in the equation. You can see it in the attached case.sif.

Thanks again for your help.

Hello, Thanks for your answers, To put convection helped, I already got a more convincing result, but not yet very different. For the k-epsilon, I'm quite ignorant. I tried to figure it out, especially from the elmersolvermanual.pdf, but it's not described. I tried quickly a naive approach, putting ...

Hello, I'm trying to simulate the transportation of gas inside volumes. I tried to base myself on the tutorials, but I'm not sure I did it right. I putted all walls on no slip, an entrance and a exit for the gas as in the tutorial. For the simulation I used the transient and BDF setups. You can find...
