Structure storing the parameters for solving the Navier-Stokes system.
| il_algo_atol |
Similar to il_algo_rtol but in the case of an absolute tolerance factor.
| il_algo_dtol |
Similar to il_algo_rtol but in the case of a divergence tolerance factor. (default 1e3)
| il_algo_rtol |
Relative tolerance factor of the linear and inner system used to solve either the Oseen or the Stokes system. This algorithm is for instance an Uzawa or GKB algorithm. This is incorporated in a non-linear process in case of Navier–Stokes equations.
| il_algo_verbosity |
Level of verbosity related to the inner linear system
Level of verbosity related to the non-linear algorithm
| n_max_il_algo_iter |
Maximal number of iterations to solve the inner linear system
| n_max_nl_algo_iter |
Maximal number of iterations for the Picard algorithm used to handle the non-linearity arising from the advection term.
