This readme file is associated with the Physics of Fluids paper entitled 
"An inertial range model for the three-point third-order velocity 
correlation," by Chang and Moser (2007). The material here provides the 
complete definition of the inertial range 3-point 3rd-order correlation, 
along with example software designed to evaluate the model. For further 
details see the documentation in Tijk_define.pdf, and comments in the files.
Also check for possible updates at http://turbulence.ices.utexas.edu

The files included here are as follows:

basisdata.txt - contains the data describing the 5 basis functions for
                the correlation model

evalTijk.f90 - module of subroutines and functions including those below:
  subroutine read_basis - reads in basis function data, 
                          e.g. from "basisdata.txt"
  subroutine build_composite - given coefficients of the basis
                               functions, sets up composite function (model)
  double precision function eval_composite - evaluates the model for
                                             given component (i,j,k) and 
                                             separation (r,s), returning 
                                             the value of the correlation

eval_2pt_3or_tophat.f90 - example program using evalTijk.f90 to evaluate
                          the correlation and it's integral (filter)

eval_2pt_3or_tophat.txt - example output from eval_2pt_3or_tophat.f90
