Detailed Description
... the abstract base class for element typesMember Function Documentation
| void sfem::element::ET::getSimplices | ( | ) | [protected] |
an abstract routine which subdivides the element into simplices. it returns the number of simplices (number) and creates memory for the output ('points'). points will be a matrix (4*number), each column is a simplex whereby the local point indices are stored.
| const ushort& sfem::element::ET::numNodes | ( | ) | const [inline] |
returns the specific integration point data
- Parameters:
-
intpt ... number of intpt returns the number of nodes
| const std::vector<ushort>& sfem::element::ET::simplexDecomposition | ( | ) | const [inline] |
returns the interpolation function values at the given natural coordinate, given a node_list with indices to _REST_MACRO_ node_table [node_list[i]] obbtaining the nodal coordinates and displacements. in: nat_coor[3], node_list[num nodes], out: coor[3], disp[6]. The default implementation does: x=sum(i=1..n, shape(i,r)*nodal_x(i)), returns the interpolation function derivatives at the given natural coordinate, derived by the natural coordinates, given a node_list with indices to _REST_MACRO_ node_table [node_list[i]], obbtaining the nodal coordinates and displacements derivatives. in: nat_coor[3], node_list[num nodes], out: coor[3*3], disp[3*6], matrices stored in the vector form (dx1/dr,...,dx3/dr, dx1/ds,...,dx3/ds, dx1/dt,...,dx3/dt) The default implementation does: x_der=sum(i=1..n, shape_der(i,r)*nodal_x(i)),
| void sfem::element::ET::sortSimplexPoints | ( | ) | [protected] |
this methods resorts the simplex-points such that they have positive volume. It must be called after getSimplices() and will be called automatically by generateTopology().
