Member Data Documentation

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 117 of file rb_temporal_discretization.h.

unsigned int libMesh::RBTemporalDiscretization::_current_time_step [private]

The current time-step.

Definition at line 105 of file rb_temporal_discretization.h.

Real libMesh::RBTemporalDiscretization::_delta_t [private]

The time-step size.

Definition at line 91 of file rb_temporal_discretization.h.

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 100 of file rb_temporal_discretization.h.

unsigned int libMesh::RBTemporalDiscretization::_n_time_steps [private]

The number of time-steps.
