Detailed Description

data structure for finite element entity

It keeps that about indices of degrees of freedom, dofs data, base functions functions, entity side number, type of entities, approximation order, etc.

Examples

mofem/atom_tests/forces_and_sources_testing_users_base.cpp.

Definition at line 40 of file EntitiesFieldData.hpp.

Constructor & Destructor Documentation

EntitiesFieldData() [1/2]

MoFEM::EntitiesFieldData::EntitiesFieldData

(

const EntityType

type

)

Construct EntitiesFieldData for given entity type.

Parameters

type	Entity type (MBVERTEX, MBEDGE, MBTRI, MBTET, etc.)

Definition at line 75 of file EntitiesFieldData.cpp.

                                                    {
  constructor_data(this, type);

Member Function Documentation

baseSwap()

MoFEMErrorCode MoFEM::EntitiesFieldData::baseSwap ( const std::string &  field_name, const FieldApproximationBase  base  )

virtual

Swap approximation base.

Bernstein-Bezier (BB) base is not hierarchical, and is calculated for particular field, since it all shape functions change with the order. BB base is precalculated for every field, and when user push operator with particular field using BB base, pointers to shape functions and BaseDerivatives of shape functions are set to particular location, once operator is executed, pointers are switch back to its original position.

getNSharedPtr(base) <=== getBBNSharedPtr(field_name); // DO OPERATOR WORK getNSharedPtr(base) ==> getBBNSharedPtr(field_name);

Parameters

field_name	Name of the field for which to swap base
base	Approximation base type to swap

Returns

MoFEMErrorCode Error code (0 on success)

Definition at line 156 of file EntitiesFieldData.cpp.

                                                                              {
  MoFEMFunctionBegin;
  // Note: Do not swap bases on entities sets
  for (int tt = MBVERTEX; tt != MBENTITYSET; ++tt) {
    auto &ent_data = dataOnEntities[tt];
    for (auto &side_data : ent_data)
      CHKERR side_data.baseSwap(field_name, base);
  }
  MoFEMFunctionReturn(0);
}

resetFieldDependentData()

MoFEMErrorCode MoFEM::EntitiesFieldData::resetFieldDependentData ( )

inline

Reset data associated with particular field name.

Returns

MoFEMErrorCode Error code (0 on success)

Definition at line 127 of file EntitiesFieldData.cpp.

                                                          {
  MoFEMFunctionBegin;
  for (EntityType t = MBVERTEX; t != MBMAXTYPE; t++)
    for (auto &e : dataOnEntities[t])
      CHKERR e.resetFieldDependentData();
  MoFEMFunctionReturn(0);
}

setElementType()

MoFEMErrorCode MoFEM::EntitiesFieldData::setElementType ( const EntityType  type )

virtual

Set element type and initialize data structures.

Parameters

type	Entity type to set

Returns

MoFEMErrorCode Error code (0 on success)

Reimplemented in MoFEM::DerivedEntitiesFieldData.
