Public Attributes | |
| const unsigned int | nr_threads_max = 0 |
| If greater than zero, limits the amount of threads used in the simulations. | |
| const double | ep_0 = permittivity_fs |
| The permittivity of free space. | |
| const double | d = 0.2 |
| The width of the rectangle around the origin in the second mesh (half-circle). | |
| const double | rd = sqrt(2) * d |
| The radius of the circle that encloses the rectangle in the middle of the mesh. | |
| double | a = 0.5 |
| The radius of the tube in the two- dimensional version of the problem or the radius of the sphere in the three- dimensional problem. More... | |
| double | b = 1.0 |
| The radius of the outer boundary of the problem domain. | |
| const double | kappa_f = ep_0 * b / (a * (b - a)) |
| The surface free-charge density. | |
| const types::boundary_id | bid = 1 |
| The ID of the boundary of the problem domain. | |
| const double | eps = 1e-12 |
| Two values in double format are considered to be equal if the absolute value of their difference is less than eps. | |
| const bool | print_time_tables = false |
| If set to true, the program will print time tables on the screen. | |
| const bool | project_exact_solution = false |
| If set to true, the program will project the exact solution. More... | |
| const bool | 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. More... | |

| const double | pi |
| The ratio between the circumference and the diameter of any circle, \(\pi\). More... | |
| const double | c = 299792458.0 |
| The speed of light in free space, \(c\). | |
| const double | permeability_fs = 4.0 * pi * 1.0e-7 |
| The permeability of the free space, \(\mu_0\). | |
| const double | permittivity_fs = 1.0 / (std::pow(c, 2) * permeability_fs) |

| double SettingsSCHAXI::a = 0.5 |
The radius of the tube in the two- dimensional version of the problem or the radius of the sphere in the three- dimensional problem.
on which the free- charge is located.

| const bool SettingsSCHAXI::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 111 of file settings.hpp.
| const bool SettingsSCHAXI::project_exact_solution = false |
If set to true, the program will project the exact solution.
The exact solution 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.
