Laminar flux

libia87 · May 7, 2012, 04:55

HI!

I want to simulate a laminar flux in the tutorial "buoyantboussinesqsimplefoam". I change the RASProperties:

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "constant";
object RASProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

RASModel laminar;

turbulence off;

printCoeffs on;

// ************************************************** *********************** //

My question is if it's sufficient to do this to simulate a laminar flux,

thanks!!!

you should change turbulenceProperties to laminar

in this tutorial there isn't turbulenceProperties, in /constant there are "g", "RASProperties" and "transportProperties"

Dear libia
ye that is enough. You can check that your solver will not solve k and epsilon equations and your nut file has constant value. And you can delete them from your 0/ directory.
