difference between U().boundaryField()[patchI] and U().boundaryField()[patchI].patchI
Hi:
I am wondering if any one know the difference between U().boundaryField()[patchI] and U().boundaryField()[patchI].patchInternalField()? and the difference between aMesh().faceAreaNormals() and aMesh().faceAreaNormals().internalField() in openfoam-1.6-ext.Thanks |
your first version gives you the values on the patch surface whereas the second version returns the values in the cells next to the surface.

What values/fields have you compared? What happens if you compare the cell center coordinates (.C(), http://www.cfd-online.com/Forums/ope...l-centers.html )?

When do you print out the values of the patchInternalField. Are you sure there is no call to the solver or some boundary.correct()? Otherwise the internal values would be modified before stored in the output files.
