◆ A_0

const double SettingsMWR::A_0
Initial value:
=
0.25 * mu_0 * J_f * a * a * log(exp(mu_r) * (b * b) / (a * a))
const double b
The radius of the outer boundary of the problem domain.
Definition: settings.hpp:75
const double a
The radius of the wire.
Definition: settings.hpp:70
const double mu_r
The relative permeability of the material of the wire.
Definition: settings.hpp:49
const double mu_0
The permeability of free space.
Definition: settings.hpp:39
const double J_f
The current density.
Definition: settings.hpp:44

A constant used to compute the exact solution.

Definition at line 80 of file settings.hpp.

◆ log_cg_convergence

const bool SettingsMWR::log_cg_convergence = false

If set to true, saves the residual at each iteration of the CG solver. The names of the files fit the following wildcard *_cg_convergence.csv.

The residuals are saved into the subdirectories of ./ Data/ directory.

Definition at line 128 of file settings.hpp.

◆ project_exact_solution

const bool SettingsMWR::project_exact_solution = false

If set to true, the program will project the exact solution.

The exact solutions will be modeled on the same mesh and by the same finite elements that are used to model the solution. The projected exact solution will be saved in the vtu file next to the solution. This option can be useful when debugging.
