Fvc H

Chapter 1. The files fvc.h includes

This file brings into the code a host of tools for finding explicit derivatives. This file reads the following

 
#include "fv.H"
#include "surfaceInterpolate.H"
#include "fvcVolumeIntegrate.H"
#include "fvcSurfaceIntegrate.H"
#include "fvcAverage.H"
#include "fvcReconstruct.H"
#include "fvcDdt.H"
#include "fvcDDt.H"
#include "fvcD2dt2.H"
#include "fvcDiv.H"
#include "fvcFlux.H"
#include "fvcGrad.H"
#include "fvcMagSqrGradGrad.H"
#include "fvcSnGrad.H"
#include "fvcCurl.H"
#include "fvcLaplacian.H"
#include "fvcSup.H"
#include "fvcMeshPhi.H"

As shown above file includes a bunch of tool providing other files. The following table specifies which tools are specified by which file.
