Dumux::GstatRandomField< GridView, Scalar > Class Template Reference

Creating random fields using gstat. More...

#include <dumux/material/gstatrandomfield.hh>

Description

template<class GridView, class Scalar>
class Dumux::GstatRandomField< GridView, Scalar >

gstat is an open source software tool which can (among other things) generate geostatistical random fields (see http://www.gstat.org or [67]).

To use this class, execute the installexternal.py from your DuMuX root directory or download, unpack and install the tarball from the gstat-website. Then rerun cmake (in the second case set GSTAT_ROOT in your input file to the path where gstat is installed).

	Creates a new field with random variables, if desired. Otherwise creates a data field from already available data. For the random field generation three files are necessary. More...

elementMapper	Maps elements of the given grid view

Member Function Documentation

create()

template<class GridView , class Scalar >

void Dumux::GstatRandomField< GridView, Scalar >::create ( const std::string &  gstatControlFile, const std::string &  gstatInputFile = "gstatInput.txt", const std::string &  gstatOutputFile = "permeab.dat", FieldType  fieldType = FieldType::scalar, bool  createNew = true  )

inline

A gstatControlFile in which all commands and in/output files for gstat are specified. A gstatInputFile contains all coordinates (cell centers) of the grid, so that gstat can perform its random realization. The filename must be same as in the gstatControlFile. A gstatOutputFile in which gstat writes the random values to this file. The filename must be the same as in the gstatControlFile.

Parameters

fieldType
gstatControlFile	name of control file for gstat
gstatInputFile	name of input file for gstat
gstatOutputFile	name of the gstat output file
createNew	set true to create a new field
