changeDictionaryDict post-processing wall>patch
Hi everyone,
Short explanation: Is there a way of changing boundary patch type after running your case? I need to go from wall to patch in order to sample my surfaces
Long:
After doing snappyHexMesh it makes my stl objects into walls. I've run my case and now want to sample the pressure on the surface of my stl walls with sampleDict.
Code:
/*--------------------------------*- C++ -*----------------------------------*\
| ========= | |
| \\ / F ield | OpenFOAM: The Open Source CFD Toolbox |
| \\ / O peration | Version: 2.3.0 |
| \\ / A nd | Web: www.OpenFOAM.org |
| \\/ M anipulation | |
\*---------------------------------------------------------------------------*/
FoamFile
{
version 2.0;
format ascii;
class dictionary;
object sampleDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
setFormat raw;
surfaceFormat vtk;
interpolationScheme cellPoint;
// Fields to sample.
fields
(
p
);
sets
(
);
surfaces
(
cubes
{
type wall;
patches ("cubes");
}
);
// *********************************************************************** //
But it won't sample a wall. So need to use changeDictionaryDict to change the constant/polyMesh/boundary for cubes from wall to patch.

FoamFile

format ascii;

object changeDictionaryDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
dictionaryReplacement
{
boundary
{
cubes
{
type patch;
}
}
}
// ************************************************************************* //
This doesn't work. |
