Hi all,
Does anyone have any suggestion as to how to define a volScalarField that is the distance to the wall patches in the mesh.
tried:

#include "wallDist.H"

...bla bla

volScalarField d
(
IOobject
(
"d",
runTime.timeName(),
runTime,
IOobject::NO_READ,
IOobject::NO_WRITE
),
mesh,
dimensionedScalar("d", dimLength, SMALL),
calculatedFvPatchScalarField::typeName
);

d = wallDist(mesh);

...does not compile...
Error---->(
wallDistance.C: In function âint main(int, char**)â:
wallDistance.C:43: warning: use of old-style cast
/home/radu/OpenFOAM/OpenFOAM-1.4/src/finiteVolume/lnInclude/wallDist.H:99: error: âFoam::wallDist::wallDist(const Foam::wallDist&)â is private
wallDistance.C:43: error: within this context
make: *** [Make/linuxGcc4DPOpt/wallDistance.o] Error 1



)


Is this going to give me the minimum of the distance (say if I have more than one patch or I have two connected wall patches like in a corner)?
Cheers,
Radu

Try d = wallDist(mesh).y()

Thanks Eugene,
Seems to work fine. Tried it with icoFoam/cavity
and OK.

Hi all,

I have a similar query as posted on this thread. Along with the wall distance how do i get the vector joining the point in the domain to the point on the wall?

Thanks and Regards,
