A Predictor-Corrector Scheme For Vortex Identification
, 1994
"... A new algorithm for identifying and characterizing vortices in complex flows is presented. The scheme uses both the vorticity and pressure fields. A skeleton line along the center of a vortex is produced by a two-step predictor-corrector scheme. The technique uses the vector field to move in the dir ..."

Predictor-Corrector Schemes for Visualization of Smoothed Particle Hydrodynamics Data
"... Abstract—In this paper we present a method for vortex core line extraction which operates directly on the smoothed particle hydrodynamics (SPH) representation and, by this, generates smoother and more (spatially and temporally) coherent results in an efficient way. The underlying predictor-corrector ..."

scheme is general enough to be applied to other line-type features and it is extendable to the extraction of surfaces such as isosurfaces or Lagrangian coherent structures. The proposed method exploits temporal coherence to speed up computation for subsequent time steps. We show how the predictor-corrector

A Predictor-Corrector Method for the Numerical Simulation of Sea Pollution!
, 1975
"... The behaviour of pollutants in the sea is described by parabolic equations with dominant advection terms, mixed derivatives and non-linear interaction terms; these equations are solved by a special predictor-corrector scheme, consisting of 3 distinct steps. The mixed derivative is split up into seco ..."

On Mehrotra-type predictor-corrector algorithms
, 2005
"... In this paper we discuss the polynomiality of a feasible version of Mehrotra’s predictor-corrector algorithm whose variants have been widely used in several IPM based optimization packages. A numerical example is given that shows that the adaptive choice of centering parameter and correction terms i ..."

Numerical study of the solutions of the 3D generalized KadomtsevPetvisahvili equations for long times
- CICP Commun. Comput. Phys
"... Abstract. From a spectral method combined with a predictor-corrector scheme, we numerically study the behavior in time of solutions of the three-dimensional general-ized Kadomtsev-Petviashvili equations. In a systematic way, the dispersion, the blow-up in finite time, the solitonic behavior and the ..."

NEW PREDICTOR/CORRECTOR ALGORITHMS WITH IMPROVED ENERGY BALANCE FOR A RECENT FORMULATION OF DYNAMIC VEHICLE/STRUCTURE INTERACTION
"... A new class of predictor/corrector algorithms is proposed to solve the complex system of differential equations that arises from a Galerkin spatial discretization of the equations of motion in a recent formulation of dynamic vehicle/structure interaction. The applicability of the concept of a buildi ..."

results as proposed in the old algorithms is avoided. Accurate results from numerical simulations using the new algorithms are obtained, and there are no unstable oscillations that were observed in some other predictor/corrector schemes. The system energy balance is also better preserved compared
Composite Schemes For Conservation Laws
, 1997
"... . Global composition of several time steps of the two-step Lax-Wendroff scheme followed by a Lax-Friedrichs step seems to enhance the best features of both, although only first order accurate. We show this by means of some examples of one-dimensional shallow water flow over an obstacle. In two dimen ..."

dimensions we present a new version of Lax-Friedrichs and an associated second order predictor-corrector method. Composition of these schemes is shown to be effective and efficient for some two-dimensional Riemann problems and for Noh's infinite strength cylindrical shock problem. We also show
