Constructor & Destructor Documentation

GridStudy()

template<int dim, int nstate>

PHiLiP::Tests::GridStudy< dim, nstate >::GridStudy ( const Parameters::AllParameters *const  parameters_input )

explicit

Constructor.

Simply calls the TestsBase constructor to set its parameters = parameters_input

Member Function Documentation

initialize_perturbed_solution()

template<int dim, int nstate>

void PHiLiP::Tests::GridStudy< dim, nstate >::initialize_perturbed_solution ( DGBase< dim, double > &  dg, const Physics::PhysicsBase< dim, nstate, double > &  physics  ) const

protected

Initialize the solution with the exact solution.

This is not an issue since the discretized solution will not be the exact solution. Therefore, the residual does not start at 0.

Definition at line 49 of file grid_study.cpp.

integrate_solution_over_domain()

template<int dim, int nstate>

double PHiLiP::Tests::GridStudy< dim, nstate >::integrate_solution_over_domain ( DGBase< dim, double > &  dg ) const

protected

L2-Integral of the solution over the entire domain.

Used to evaluate error of a functional.

Definition at line 65 of file grid_study.cpp.

run_test()

template<int dim, int nstate>

int PHiLiP::Tests::GridStudy< dim, nstate >::run_test ( ) const

virtual

Manufactured grid convergence.

Will run the a grid convergence test for various p on multiple grids to determine the order of convergence.

Expecting the solution to converge at p+1. and output to converge at 2p+1. Note that the output solution currently convergens slightly suboptimally depending on the case (around 2p). The implementation of the boundary conditions play a large role on this adjoint consistency.

The exact solution is given by the Physics module.

Implements PHiLiP::Tests::TestsBase.

warp()

template<int dim, int nstate>

dealii::Point< dim > PHiLiP::Tests::GridStudy< dim, nstate >::warp ( const dealii::Point< dim > &  p )

staticprotected

Warps mesh into sinusoidal.

Useful to check non-cartesian linear meshes
