Abstract:

PLUTO Poisson Laplace U TFI Orthogonal, is a three dimensional gridding and smoothing program developed in-house at WLFIMM. Its purpose is to 1 generate three dimensional grids from the six two dimensional faces of a computational grid, 2 check grid quality, 3 smooth grids to improve spacing, smoothness and orthogonality, and 4 output grids in user selected ascii or binary formats. Initial grids are established by PLUTO with a three-dimensional algebraic transfinite interpolation TFI scheme. For many application, where simple block shapes and spacings are used, an algebraic grid may be sufficiently smooth and orthogonal for use. As a check, QBERT Quantitative Block Error Tester is run on each block to generate diagnostics about the grids spacing, skewness and right-handedness.
