run() [1/2]

template<int dim, int degree_finite_element>

void DTR_mf::DTRProblem< dim, degree_finite_element >::run	(	unsigned int	n_initial_refinements = 3,
		unsigned int	n_cycles = 9 )

Compute the solution of the DTR problem.

This method executes the setup, right-hand side assembly, solution, and output steps for the DTR problem for a given number of times. The number of initial refinements determines the number of cells in the mesh at the first solution, and the number of executed cycles determines the number of additional refinements performed.

Parameters

n_initial_refinements	The number of initial refinements to perform on the mesh.
n_cycles	The number of solutions to compute by adding a refinement at each iteration.

run() [2/2]

template<int dim, int degree_finite_element = 2>

void DTR_mf::DTRProblem< dim, degree_finite_element >::run	(	unsigned int	n_initial_refinements = 3,
		unsigned int	n_cycles = 9 )

Compute the solution of the ADR problem. It executes the setup, rhs assembly, solve, and output_results steps for the solution of the problem for a given number of times. The given number of initial refinements determines the number of cells in the mesh at the first solution as initial number of cells = dim^(initial_refinements-dim). The number of executed cycles is n_cycles - dim.

Parameters

n_initial_refinements	the number of initial refinements to perform on the mesh.
n_cycles	the number of solutions to compute adding a refinement at each iteration.
