it is worth to take a time to read.

Tetra mesh with prism layers generated in SALOME.

Let us suppose you have the following matrices:

x(nx,ny,nz): x coordinates of your grid

y(nx,ny,nz): y coordinates of your grid

z(nx,ny,nz): z coordinates of your grid

dudx(nx,ny,nz): x-wise derivative of x-wise velocity component

dudy(nx,ny,nz): y-wise derivative of x-wise velocity component
.
.
.
dwdz(nx,ny,nz): z-wise derivative of z-wise velocity component

This is, more or less, how i would...

there is a basic MATLAB tool to handle unstructured finite volume grids (fluent .msh or .cas files) and to perform basic interpolations, gradient computations, plots etc. No actual FV computation is ever performed or implemented, however, the main structure of the code is clearly there.

GENERAL DESCRIPTION

The tool is actually a collection of functions, grouped by tasks...

A paper produced for a national conference. Some basic details of the LES in Fluent are covered, together with the main setup:
