Yes, I saw these pressure wiggles as well in my cases, but I didn't pay too much attention to them. I don't know if they are due to bad numerical settings or some bug in the code. Perhaps you can write a bug report with that small test case.

Dear ArathoN and Philipp,

I am trying to simulate square duct problem (Re=3500) using cyclic inlet outlet with fvOptions. I am using OpenFOAM 4.1 with simpleFoam with k-epsilon model.

I am not getting convergence for pressure & cross stream velocities. However, I am getting fully developed velocity profile in stream wise direction. Also, gradP term reaches steady state.

Could you please give me your suggestions to improve the convergence?

The case file that I used is available in the following link:

https://github.com/vino-123/square_duct_cyclic_inout

The following are the convergence I got with above case settings.

Convergence:

Thank you very much for your help.
