Member Function Documentation

◆ assemble_matrix()

void WilsonPenzienNewmark::assemble_matrix ( )

overridevirtual

Assemble the global effective matrix A in AX=B. For FEM applications, it is often a linear combination of stiffness, mass, damping and geometry matrices.

Reimplemented from Newmark.

Here is the call graph for this function:

◆ assemble_resistance()

void WilsonPenzienNewmark::assemble_resistance ( )

overridevirtual

Reimplemented from Newmark.

Here is the call graph for this function:

◆ clear_status()

void WilsonPenzienNewmark::clear_status ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ commit_status()

void WilsonPenzienNewmark::commit_status ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ initialize()

int WilsonPenzienNewmark::initialize ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ print()

void WilsonPenzienNewmark::print ( )

overridevirtual

Reimplemented from Newmark.

◆ process_constraint()

int WilsonPenzienNewmark::process_constraint ( )

overridevirtual

The main task of this method is to apply constraints (of various forms implemented in various methods). Combinations of different types need to be considered: 1) homogeneous, 2) inhomogeneous, 3) linear, 4) nonlinear. Combinations of different methods need to be considered: 1) penalty, 2) multiplier. On exit, the global stiffness matrix should be updated, the global residual vector should be updated.

Reimplemented from Integrator.

Here is the call graph for this function:

◆ reset_status()

void WilsonPenzienNewmark::reset_status ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:
