Member Data Documentation

_control

std::vector<Real> libMesh::RBTemporalDiscretization::_control

private

The RHS control (scalar function of time). A function h(t) that is used in the RHS as h(t)*f(x, ). See Martin Grepl's thesis

Definition at line 121 of file rb_temporal_discretization.h.

_current_time_step

unsigned int libMesh::RBTemporalDiscretization::_current_time_step

private

The current time-step.

Definition at line 109 of file rb_temporal_discretization.h.

_delta_t

Real libMesh::RBTemporalDiscretization::_delta_t

private

The time-step size.

Definition at line 95 of file rb_temporal_discretization.h.

_euler_theta

Real libMesh::RBTemporalDiscretization::_euler_theta

private

The parameter that determines the generalized Euler scheme discretization that we employ. euler_theta = 0 —> Forward Euler euler_theta = 0.5 —> Crank-Nicolson euler_theta = 1 —> Backward Euler

Definition at line 104 of file rb_temporal_discretization.h.

_n_time_steps

unsigned int libMesh::RBTemporalDiscretization::_n_time_steps

private

The number of time-steps.
