PLUTO 3-D Grid Generator (User's Manual)

Abstract

PLUTO (Poisson Laplace U TFI Orthogonal), is a three dimensional gridding and smoothing program developed in-house at WL/FIMM. 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 grid's spacing, skewness and right-handedness.
