Displacement Diffusor
 

Dear all,

I'm facing the following problem. I'm trying to include a displacement diffusor in my simulation but it doesn't work. Is there any trick how to set up these kind of diffusors. You can find a picture of the attributes as well as my q1 file and my result file - in the result file you can see that there is no entry for the diffusor in the R1 column.

cheers

change the pressure
 

try to change the external pressure to see if you can get some flow in

thanks for your reply.

why should changing the external pressure solve this problem? I defined a fixed volume flow. The diffusor should work with this volume flow no matter which external pressure I set.
