Hi all,

I got stuck with a hopefully simple calculation. With a code sniplet out of this forum (dont remember where I found it) and some research, I try to calculate the distance of a cell center and face center, belonging to a patch cell called faceCelli.

Code:
forAll(myPatch, facei)
              {
              label faceCelli = myPatch.faceCells()[facei];
              wallList.resize(wallList.size()+1);
              wallList[wallList.size()-1]=faceCelli;

              // ...

              faceArea+=mesh.magSf()[faceCelli];
      
              cellMarker[faceCelli]=1.0;
              
              C[faceCelli]=mesh.C()[faceCelli];
              Cf[faceCelli]=mesh.Cf()[facei];     
              
              
              cellFaceDistanceVector[faceCelli] =C[faceCelli] - Cf[facei];  //Cf[faceCelli] wont work either
              cellFaceDistance[faceCelli]= mag(cellFaceDistanceVector[faceCelli]);

The distance between cell center and cell face center becomes way too large.
As I can see in my timeName.C and .Cf, they are both calculated on the correct cell ID. So why wont I get the correct distance?

Best regards
Martin
