A Method for Unstructured Mesh-to-Mesh Interpolation

reportActive / Technical Report | Accession Number: ADA531390 | Open PDF

Abstract:

An efficient method for unstructured mesh-to-mesh interpolation is described. This method uses a binary space partitioning tree to sort the elements of the source mesh. Using this tree data structure the source mesh elements can be efficiently searched to find the nearest element for each of the destination mesh points. Once found, the nearest source mesh element is used to compute barycentric coordinates which are then used as weighting coefficients for the interpolation.
