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?

Thanks again |

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

simpleFoam uses Newtonian flui
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 afterwards turbulence off?

And what about all the other files in which parameters for the turbulent calculation are used? |
Sure switch turbulence off if
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? |
It's not a time step, just an
It's not a time step, just an iteration counter - you can set the deltaT to whatever you like. I usually use 1.

Hi,

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? |
