Member Function Documentation
◆ refresh()
template<typename Real = double>
|
overridevirtual |
Causes that the monitor prints out the status of the solver.
Implements TNL::Solvers::SolverMonitor.
◆ setIterations()
template<typename Real = double>
| void TNL::Solvers::IterativeSolverMonitor< Real >::setIterations | ( | const IndexType & | iterations | ) |
Set number of the current iteration.
- Parameters
-
iterations is number of the current iteration.
◆ setNodesPerIteration()
template<typename Real = double>
| void TNL::Solvers::IterativeSolverMonitor< Real >::setNodesPerIteration | ( | const IndexType & | nodes | ) |
Set the number of nodes of the numerical mesh or lattice.
This can be used to compute the number of nodes processed per one second.
- Parameters
-

-
stage is name of the solver stage.
◆ setTime()
template<typename Real = double>
| void TNL::Solvers::IterativeSolverMonitor< Real >::setTime | ( | const RealType & | time | ) |
Set the time of the simulated evolution if it is time dependent.
This can be used for example when solving parabolic or hyperbolic PDEs.
- Parameters
-
time time of the simulated evolution.
◆ setTimeStep()
template<typename Real = double>
| void TNL::Solvers::IterativeSolverMonitor< Real >::setTimeStep | ( | const RealType & | timeStep | ) |
Set the time step for time dependent iterative solvers.
- Parameters
-
timeStep time step of the time dependent iterative solver.
◆ setVerbose()
template<typename Real = double>
| void TNL::Solvers::IterativeSolverMonitor< Real >::setVerbose | ( | const IndexType & | verbose | ) |
Set up the verbosity of the monitor.
- Parameters
-
verbose is the new value of the verbosity of the monitor.
