Hi, I am simulating an aerofoil in a wind tunnel. I have done the simulation and want to see the velocity and pressure distributions on and around the aerofoil. However, the wind tunnel is filled and I cant see the aerofoil to be able to analyse it fully.

Thanks

if you go to contours and then hit set up, you can choose on which face you want to display the quantity of interest.

Tried that but I can only view the inlet velocity, outlet pressure, interior surrounding surface and wall surrounding surface. The only one which will let me view the aerofoil is the interior surrounding surface, however it comes with the wind tunnel.

I used the boolean option to cut out the section of the aerofoil against the wind tunnel. Does that have something to do with the reason why I cant individually view the side of the aerofoil?

I see, the problem is that during mesh generation you have to specify each boundary separately (that you want to look at), otherwise fluent (or infact any other post processor) will not be able to figure out by itself what exactly you want to look at. that is true even if they have the same sort of boundary condition (wall in this case).
would you be able to provide the *.cas and *.dat file from fluent to have a look?

The file with the aerofoil and wind tunnel?

yes, the file when you save the project within fluent (two files, with *.dat and *.cas ending)

I only seem to have the .wbpj file which I open up in workbench.

Any ideas?

I have meshed the aerofoil individually and got a result. However, as you can see from the image there is low velocity where there shouldn't be (blue contours).

Any ideas as to why this is occurring?

you have a turbulent viscosity warning, which is never a good thing. are you meshing with the workbench meshing tool? have you run the mesh check inside fluent to check the quality? it could also be that the boundary conditions are set up incorrectly. but that is all very difficult to tell without sitting infront of the problem. if you go (inside fluent) to file -> write -> case and data safe the file and upload them somewhere (you can send the link in a private message if you prefer) i could have a look at it
