Problem with Fluctuationg Pressure Field in opneFOAM (Repeated Post)

owayz · August 9, 2012, 10:36

Hallo Foamers,
This issue have been posted many times on this forum. But I haven't seen any interest from our experienced forum users. That is why I thought about posting it again (in a desperate effort to get some help).
Its the same problem about unphysical pressure field using LES. I have tried many things which I have mentioned here on this thread as well.
Post about problems and solutions that I have tried till now.

Now to save time I am trying to run the cylinder case with 2D LES something like pitzDaily (2D LES compressible with rhoPimpleFOAM).

I will upload my case mesh and everything in dropbox and share it soon on the forum.

Regards,
Awais

Here is the dropbox link to my case. Actually instead of a full 3D simulation I am trying a 2D one, to see if the boundary conditions work, and if I could get a proper solution for the pressure.
