void Element::get_bounding_box ( BoundingBox & bounding_box ) const

Computes bounding box of element (OBSOLETE) ??

Definition at line 205 of file elements.cc.

Here is the caller graph for this function:

BoundingBox & Element::get_bounding_box_fast ( BoundingBox & bounding_box ) const

Here is the caller graph for this function:

unsigned int Element::n_sides_by_dim ( unsigned int side_dim )

Count element sides of the space dimension side_dim.

Definition at line 146 of file elements.cc.

double Element::quality_measure_smooth ( )

Quality of the element based on the smooth and scale-invariant quality measures proposed in: J. R. Schewchuk: What is a Good Linear Element?

We scale the measure so that is gives value 1 for regular elements. Line 1d elements have always quality 1.

const SideIter Element::side ( const unsigned int loc_index ) const

inline

Definition at line 52 of file element_impls.hh.

double Element::tetrahedron_jacobian ( ) const

Computes the Jacobian of the element. J = det ( 1 1 1 1 ) x1 x2 x3 x4 y1 y2 y3 y4 z1 z2 z3 z4

Here is the caller graph for this function:

vector<arma::vec3> Element::vertex_list ( )

inline

Return list of element vertices.
