Hello Dear All,
I use buoyantBoussinesqPimpleFoam to solve incompressible airflow around buildings. I have been trying to apply cyclic boundary condition (BC) in span-wise direction and cyclic pressure jump BC (fan) in stream-wise or inlet and outlet direction to initiate flow. However, the incompressible solvers in OpenFOAM want pressure as a fixed value at inlet or outlet to work properly. If all cyclic conditions are applied then the solution diverges at a corner of the domain. Have anyone found a work around this issue? I was suggested to use a compressible solver, but for my case I prefer to use an incompressible solver.
Thanks,
Amir A. Aliabadi
Can you print a screenshots?

Meanwhile have a look to the attaced pdf.
Hello Franco,
Thank you for the information. You can see the code and screen shots in the following link. Please let me know If any ideas occur to you,

I can't see the images. I'm not registered. Please post the images here.

Hi France, here are the information including picture, solver, and case file ...
Hi Amir,
Were you able to solve the issue. I am also trying to run buoyantBoussinesqPimpleFoam solver. I observe the sudden unrealistic velocities creeping in from boundaries.
Kindly let me know if you found a work around.
Thanks
