Face and point ordering during interpolation
 

Hi all,

I have two questions concerning the interpolation from faces to points and getting the corresponding point coordinates.
To move the boundary of a movingMesh case, I have calculated the displacement/motion at the face centers on the moving boundary patch (stored in volScalarField hbVol.boundaryField()[patchi]).

As I need the point displacement/motion at the points and not the faces, I used primitivePatchInterpolation faceToPointInterpolate on the face values. The point values are now used to modify the pointdisplacement/motionU file at the boundary patch within the solver, by doing e.g.

My questions are:
1. How do I know or can make sure that faceToPointInterpolate is giving the same order of the points that is used in pointDisplacement file?

2. How can I get the x,y,z coordinates of these boundary patch points, and again make sure that the point order is right?
Something like mesh.boundaryMesh()[patchi].points()[pointI].x() does not give me the right points.

Ok, to answer my questions:

2. Point coordinates on the patch (e.g. for x) are found using mesh.boundaryMesh()[patchi].localPoints()[pointI].x().

1. I have checked the point order (sorry, not ordering!) by looping 1. over mesh.boundaryMesh()[patchi].localPoints() and 2. over the point list received from face to point interpolation. Result: Order is equal!

Greetings,
