Extrapolation cell to vertex!

Hi,
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? Regards Anders |

Check-out the following references !
1. D.G. Holmes and S.D. Connell, "Solution of 2D Navier-Stokes equations on unstructured adaptive grids", AIAA paper 89-1932 in Proc. AIAA 9th CFD Conference, 1989. 2. N.T. Frink, "Upwind scheme for solving the Euler equations on unstructured tetrahedral meshes, AIAA J. 30(1), 70 (1992). 3. N.T. Frink and S.Z Prizadeh, "Tetrahedral finite-volume solutions to the Navier-Stokes equations on complex configurations" in Proc. 10th International Conference on Finite Elements in Fluids, Tuscon, AZ, USA, 1998. Ref. [1] talks about the method of Lagrange multipliers and Ref. [2] deals with inverse distance approach. For better understanding have a look at Ref.[3]. Jawahar |
