Hey Foamers,

I simulate a internal pipe gas flow through a high porous structure for different inlet velocities with simpleFoam.

I start with Uin = 0.1 and and go to Uin=1.5 m/s.
For a velocity of 1m/s I reach convergence.
For higher velocities, the solution does not convergence.

My question now is: Does this come from a too coarse mesh (already did a grid study for many refinements) or is it because of strating turbulence?
Can anybody tell me, how I can identify turbulence in comparison to a mesh problem?

Thanks a lot for your info!

Best regards
