Detailed Description

This finite element implements a rectangular element that uses evaluation not only of the values but also the gradient and the mixed second derivative at each corner.

Therefore a polynomial space of dim = 16 is needed. The associated space is implemented in C1Poly.

This yiels discontinuous differentiable global functions.

Transformation properties

One has to be careful using this element. On rectangular elements no problems occur. The class MyMappingQ1 should later provide a transformation onto parallelograms.

Numbering of the degrees of freedom (DoFs)

The numbering of the degrees of freedom is as follows. The numbering begins at the first corner with the degree of freedom associated with the value, then degrees of freedom for , and follow.

Member Function Documentation

std::string FE_C1::get_name

(

)

const [virtual]

Return a string that uniquely identifies a finite element. This class returns FE_C1().

Implements FiniteElement< dim >.

FiniteElement< 2 > * FE_C1::clone

(

)

const [protected, virtual]

clone function instead of a copy constructor.

This function is needed by the constructors of FESystem.

Implements FiniteElement< dim >.

std::vector< unsigned int > FE_C1::get_dpo_vector

(

const unsigned int

degree

)

[private]

Only for internal use. Its full name is get_dofs_per_object_vector function and it creates the dofs_per_object vector that is needed within the constructor to be passed to the constructor of FiniteElementData.
