Constructor & Destructor Documentation

◆ FEShape() [1/2]

FEShape ( const Element el)

Constructor for an element.

Parameters
[in]elPointer to element

◆ FEShape() [2/2]

FEShape ( const Side sd)

Constructor for a side.

Parameters
[in]sdPointer to side

Member Function Documentation

◆ getDet()

real_t getDet ( ) const

Return determinant of jacobian.

If the transformation (Reference element -> Actual element) is not affine, member function setLocal() must have been called before in order to calcuate relevant quantities.

◆ getLocalPoint() [1/2]

Point< real_t > getLocalPoint ( ) const

Localize a point in the element.

Return actual coordinates in the reference element. If the transformation (Reference element -> Actual element) is not affine, member function setLocal() must have been called before in order to calcuate relevant quantities.

◆ getLocalPoint() [2/2]

Point< real_t > getLocalPoint ( const Point< real_t > &  s) const

Localize a point in the element.

Return actual coordinates where s are coordinates in the reference element.

◆ Sh()

real_t Sh ( size_t  i,
Point< real_t s 
) const

Calculate shape function of node i at a given point s.

Parameters
[in]iLocal node label
[in]sPoint in the reference triangle where the shape function is evaluated
