Detailed Description

template<class T, class Tpw>
class Moose::MFEM::CoefficientMap< T, Tpw >

Class to manage MFEM coefficient objects representing material properties.

It can build up piecewise coefficients representing properties defined across multiple materials.

addCoefficient()

template<class T, class Tpw>

void Moose::MFEM::CoefficientMap< T, Tpw >::addCoefficient ( const std::string &  name, std::shared_ptr< T >  coeff  )

inline

Add a named global coefficient.

It must have been created with the make method on this object.

addPiecewiseBlocks()

template<class T, class Tpw>

void Moose::MFEM::CoefficientMap< T, Tpw >::addPiecewiseBlocks ( const std::string &  name, std::shared_ptr< T >  coeff, const std::vector< std::string > &  blocks  )

inline

Add piecewise material property.

The coefficient must have been created with the make method on this object.

Note: If you attempt to overwrite an existing block then an exception will be thrown and data for that property will be left in an undefined state.
