OpenFOAM Prblm "Max Number of iteration Exceeded"

Hello,

Being new to all these concepts of CAD, CFD and else, I am really impressed by this Linux distribution, thanks to the developers. Your work is fantastic.

I have one question with the use of OpenFOAM.

For my simulation, as fluid mechanics is a distant field ( more of an electrical engineer), I'm using the parameters I found in the OpenFOAM tutorial using sonicFoam "Forward Step". I would like to have some results of my geometry at transonic speed and I think it's the good solver to use (correct me if i'm wrong). My geometry is a 2D pipe with a valve inclined at 45º (extruded to have a 3D model). I created my mesh by defining Inlet, Outlet, Wall and a top/bottom symmetry plane.

Here is my problem: when I start the calculation, after a few iterations, I have an error message.

--> FOAM FATAL ERROR:
Maximum number of iterations exceeded

From function specieThermo<Thermo>::T(scalar f, scalar T0, scalar (specieThermo<Thermo>::*F)(const scalar) const, scalar (specieThermo<Thermo>::*dFdT)(const scalar) const) const

I've tried looking on other topics on other forums but I could'nt find yet what's wrong...

Thanks in advance for your help,

Hi Alex,

I know it was a long, long time ago, but could you find a solution to your problem? I'm currently facing the same problem.

Thx,

David
