Detailed Description

definition of 1D quadratic finite element.

NAME: ElmB3n1D - definition of 1D quadratic finite element

DESCRIPTION:

The class is derived from class "ElmTensorProd" and restricts the interpolation to be of order two and the number of space dimensions to equal one. That is, this is the standard 1D quadratic finite element with 3 nodes.

Most of the operations on this element type are defined through virtual functions or member functions of the base class "ElmDef".

Member Function Documentation

void ElmB3n1D::fillNodePath ( MatSimplest(int) & nodes, bool vertices_only ) [virtual]

returns an array "nodes" such that side number "s" of the element passes through the nodes "nodes(s,j)" where "j" runs from 1 to the number of nodes on the given side. In case of varying number of nodes per side, the rest of the array row is padded with zeros. The delivered data will deal with local side number "i" in row "i" of "nodes". The orientation of each side is coordinated such that the array describes a counterclockwise traversal of the element boundary. If the flag "vertices_only" is "true", only vertex nodes are returned. Otherwise, non-vertex nodes located on a side (such as midnodes) will also contribute. Reimplemented from ElmDef.
