Hi,

does someone know, whether there is a solver for:
steady-state, incompressible, laminar, Newtonian-fluids

Thanks a lot,
Anja

Sure, just run simpleFoam and switch the turbulence model to laminar.

And how do I have to do that? (I really can need the advice)

Thanks again

And what about the change from non-Newtonian fluids of simpleFoam to Newtonian fluids?

simpleFoam uses Newtonian fluid by default.
Open the "turbulenceProperties" file in the "constant" sub-directory and change the turbulence model from "RNGkEpsilon" to "laminar".

And what about all the other files in which parameters for the turbulent calculation are used?

Sure switch turbulence off if you like. The rest should just work.

As an alternate solution, I ended up writing a small variant of simpleFoam for my own work that does exactly what you want -- incompressible, Newtonian, steady-state, laminar flow -- without any additional "features" like turbulence or viscosity models.

It's a pretty trivial combination of parts from the existing OpenFOAM applications, so I can't really claim any ingenuity in creating it, but to save you the trouble of recreating it I've put a copy online here: http://dpdx.net/software/openfoam/st...w_1.0.0.tar.gz .

There's a README.txt file in the .tar.gz file that covers what bits go where to install it.

Okay, one more question on that topic.
Why do I need a time-step for a steady-state solver?

hjasak will become famous soon enough
It's not a time step, just an iteration counter - you can set the deltaT to whatever you like. I usually use 1.

Enjoy,

Hi,

I'm still using simpleFoam as laminar solver. The problem is that the calculation takes that long. I've already changed the solver for p to AMG.
Is there any suggestion for the endtime in the controldict?
