Detailed Description

Provide data structure for (tensor) field approximation.

The Field is intended to provide support for fields, with a strong bias towards supporting first and best the capabilities required for scientific computing applications. Since we work with discrete spaces, data structure has to carry information about type of approximation space, its regularity.

Field data structure storing information about space, approximation base, coordinate systems, etc. It stores additional data needed for book keeping, like tags to data on the mesh.

Each filed has unique ID and name. This data structure is shared between entities on which is spanning and DOFs on those entities.

Examples

EshelbianPlasticity.cpp, forces_and_sources_testing_users_base.cpp, and scalar_check_approximation.cpp.

getDofSequenceContainer()

SequenceDofContainer& MoFEM::Field::getDofSequenceContainer ( ) const

inline

Get reference to sequence data container.

In sequence data container data are physically stored. The purpose of this is to allocate DofEntity data in bulk, having only one allocation instead each time entity is inserted. That makes code efficient.

The vector in sequence is destroyed if last entity inside that vector is destroyed. All MoFEM::MoFEMEntities have aliased shared_ptr which points to the vector.

Not all DOFs are starred in this way, currently such cases are considered;

• DOFs on vertices. That is exploited that for H1 space, there is some fixed number of DOFs on each vertex

For other cases, DOFs are stored locally in each MoFEM::MoFEMEntities.

Returns

getNbOfCoeffs()

FieldCoefficientsNumber MoFEM::Field::getNbOfCoeffs ( ) const

Scalar field has only one coefficient, vector field in 3D has three. In general number determine space needed to keep data on entities. What coefficient means depend on interpretation and associated coordinate system. For example 3 coefficient means could be covariant or contravariant, or mean three temperatures for mixture of solid, air and water, etc.
