The mathematical technique of meshless gradient calculation was created for use in an ice-sheet model
 Entry ID: AAD_MESHLESS_GRADIENT

[ Update this Record ]

Summary
Abstract: A computationally efficient algorithm to calculate the weighting
coefficients for an arbitrary multi-dimensional distributions of points
is presented. The iterative algorithm guarantees IEEE 754 64-bit precision for
the weighting coefficients. The open source FORTRAN-90 implementation has
been optimised for a random distribution of points in 1 to 3 dimensions.
Additional functionality allows for higher precision operation and run
time optimisation for non random point distributions.
