Extrapolation cell to vertex!
I have a unstructured surface mesh (tris) with variables stored in its cell coordinates (center of the triangle). I'd like to extrapolate these cell center values to the vertices. Does anyone have any good ideas how this should be done, surely there ought to be a lot written about this. Anyone knows any good references?

Check-out the following references !

Ref.  talks about the method of Lagrange multipliers and Ref.  deals with inverse distance approach. For better understanding have a look at Ref..
