Member Function Documentation

clone()

virtual std::unique_ptr<FEMFunctionBase<Number> > CoupledFEMFunctionsx::clone ( ) const

virtual

Returns

A new copy of the function.

The new copy should be as "deep" as necessary to allow independent destruction and simultaneous evaluations of the copies in different threads.

Implements libMesh::FEMFunctionBase< Number >.

Definition at line 118 of file coupled_system.h.

  {
    return libmesh_make_unique<CoupledFEMFunctionsx>(*this);
  }

component()

Number libMesh::FEMFunctionBase< Number >::component ( const FEMContext &  context, unsigned int  i, const Point &  p, Real  time = 0.  )

virtualinherited

Returns

The vector component i at coordinate p and time time.

Note

Subclasses aren't required to override this, since the default implementation is based on the full vector evaluation, which is often correct.

Subclasses are recommended to override this, since the default implementation is based on a vector evaluation, which is usually unnecessarily inefficient.

Definition at line 133 of file fem_function_base.h.

{
  DenseVector<Output> outvec(i+1);
  (*this)(context, p, time, outvec);
  return outvec(i);
}

init_context()

virtual void libMesh::FEMFunctionBase< Number >::init_context ( const FEMContext &  )

virtualinherited

Prepares a context object for use.

Most problems will want to reimplement this for efficiency, in order to call FE::get_*() as their particular function requires.

Definition at line 73 of file fem_function_base.h.

{}

operator()() [1/4]

void libMesh::FEMFunctionBase< Number >::operator() ( const FEMContext &  context, const Point &  p, DenseVector< Number > &  output  )

inherited

Evaluation function for time-independent vector-valued functions.

Sets output values in the passed-in output DenseVector.

Definition at line 145 of file fem_function_base.h.

{
  // Call the time-dependent function with t=0.
  this->operator()(context, p, 0., output);
}

operator()() [2/4]

virtual void libMesh::FEMFunctionBase< Number >::operator() ( const FEMContext &  , const Point &  p, const Real  time, DenseVector< Number > &  output  )

pure virtualinherited

Evaluation function for time-dependent vector-valued functions.

Sets output values in the passed-in output DenseVector.

Pure virtual, so you have to override it.

operator()() [3/4]

virtual void CoupledFEMFunctionsx::operator() ( const FEMContext &  , const Point &  , const Real  , DenseVector< Number > &    )

virtual

Definition at line 123 of file coupled_system.h.

  { libmesh_not_implemented(); }

operator()() [4/4]

virtual Number CoupledFEMFunctionsx::operator() ( const FEMContext &  , const Point &  p, const Real  time = 0.  )

virtual

Returns

The scalar function value at coordinate p and time time, which defaults to zero.

Pure virtual, so you have to override it.

Implements libMesh::FEMFunctionBase< Number >.
