Functions
static tarch::la::Vector< 2, double >	exahype2::fv::getVolumeSize (const tarch::la::Vector< 2, double > &h, int numberOfVolumesPerAxisInPatch)
	We need this routine within vectorised and GPUised code.
static tarch::la::Vector< 3, double >	exahype2::fv::getVolumeSize (const tarch::la::Vector< 3, double > &h, int numberOfVolumesPerAxisInPatch)
static tarch::la::Vector< 2, double >	exahype2::fv::getFaceSize (const tarch::la::Vector< 2, double > &h, int numberOfVolumesPerAxisInPatch)
static tarch::la::Vector< 3, double >	exahype2::fv::getFaceSize (const tarch::la::Vector< 3, double > &h, int numberOfVolumesPerAxisInPatch)
static tarch::la::Vector< 2, double >	exahype2::fv::getVolumeCentre (const tarch::la::Vector< 2, double > &x, const tarch::la::Vector< 2, double > &h, int numberOfVolumesPerAxisInPatch, const tarch::la::Vector< 2, int > &index)
	In ExaHyPE's Finite Volume setup, a cell hosts a patch of Finite Volumes.
static tarch::la::Vector< 3, double >	exahype2::fv::getVolumeCentre (const tarch::la::Vector< 3, double > &x, const tarch::la::Vector< 3, double > &h, int numberOfVolumesPerAxisInPatch, const tarch::la::Vector< 3, int > &index)

static tarch::la::Vector< 3, double >	exahype2::fv::getFaceCentre (const tarch::la::Vector< 3, double > &x, const tarch::la::Vector< 3, double > &h, int numberOfVolumesPerAxisInPatch, int overlap, int normal, const tarch::la::Vector< 3, int > &index)
double	exahype2::fv::getVolumeLength (const tarch::la::Vector< 2, double > &h, int numberOfVolumesPerAxisInPatch)
	With GCC 10, it was impossible to return/copy the vector class.
double	exahype2::fv::getVolumeLength (const tarch::la::Vector< 3, double > &h, int numberOfVolumesPerAxisInPatch)
std::string	exahype2::fv::plotVolume (const double *__restrict__ Q, int unknowns)
	Helper routine that I need in the log statements.
void	exahype2::fv::validatePatch (const double *__restrict__ Q, int unknowns, int auxiliaryVariables, int numberOfVolumesPerAxisInPatch, int haloSize, const std::string &location="", bool triggerNonCriticalAssertion=true, double *minValues=nullptr, double *maxValues=nullptr)
	Just runs over the patch and ensures that no entry is non or infinite.
std::string	exahype2::fv::plotPatch (const double *__restrict__ Q, int unknowns, int auxiliaryVariables, int numberOfVolumesPerAxisInPatch, int haloSize, bool prettyPrint=false)
	Plot patch.
std::string	exahype2::fv::plotPatchOverlap (const double *__restrict__ Q, int unknowns, int auxiliaryVariables, int numberOfGridCellsPerPatchPerAxis, int haloSize, int normal, bool prettyPrint=false)
void	exahype2::fv::copyHalfOfHalo (int unknownsPlusAuxiliaryVariables, int numberOfGridCellsPerPatchPerAxis, int haloSize, int normal, bool isRightLayer, const double *__restrict__ srcQ, double *__restrict__ destQ)
	A face always holds a left and a right overlap.
