Member Data Documentation

log_cg_convergence

const bool SettingsSSOLIII::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 152 of file settings.hpp.

project_exact_solution

const bool SettingsSSOLIII::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.
