pTraits

Posted September 14, 2017 at 06:05 by kindle

Code:

int(pTraits<arg1>::rank)

just gives flexibility to all types that pTraits wapped. And rank is another static member like "one" and "zero"

Thank you so much. Today I met the pTraits in the turbulentInlet.C again. So I had a look at thread again. The codes are as follows:

Code:

        scalar rmsCorr = sqrt(12*(2*alpha_ - sqr(alpha_)))/alpha_;

        patchField =
            (1 - alpha_)*patchField

Well, well well,

correctBoundaryConditions is also called after the linear solver call automatically.

Enjoy,

Average values on Boundary Conditions

Great example of profit from the Openfoam

Then you can run patchAverage on each component:

Code:

patchAverage Ux myInlet

You can also use foamCalc to do other things like calculate the magnitude of a volVectorField:

Code:

foamCalc mag U

If you

And as of OpenFOAM 2.2, you can find more details about boundary conditions and function objects here: http://foam.sourceforge.net/docs/cpp/modules.html

What you're looking for is in the section Coupled boundary Conditions

The general idea is that:

You define

Installation of OpenFOAM 2.3.0 / 2.3.x on RHEL 5.8 without root permissions

Posted July 7, 2017 at 04:08 by kindle
Updated July 10, 2017 at 04:55 by kindle (add the right way to check the interior mesh)

Take a look at the paraview setting.

Here is a page saying that to check the mesh inside a geometry (https://openfoamwiki.net/index.php/FAQ/Postprocessing). The right thing to do is not the clip nor the slice. But
1. load the case unchecking polyhedral decomposition
2. filter : Extract Cells by Region
