Detailed Description

Structure storing the parameters for solving the Navier-Stokes system.

Field Documentation

anderson_param

anderson_param

Set of parameters to drive the Anderson acceleration (useful if the type of non-linear algorithm is set to Anderson acceleration).

il_algo_cvg

il_algo_cvg

Structure storing several tolerances and metadata to drive the convergence of the inner (linear) iterative algorithm 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 the case of Navier–Stokes equations.

il_algo_restart

il_algo_restart

Number of iterations before restarting the iterative solver associated to the inner linear system

nl_algo_cvg

nl_algo_cvg

Structure storing several tolerances and metadata to drive the convergence of the non-linear iterative algorithm used to solve te Navier-Stokes when the advection term is implicit and non linearized.

nl_algo_type

nl_algo_type

Type of algorithm used to tackle the non-linearity arising from the advection term

schur_approximation

schur_approximation

Choice of the way of preconditioning the schur approximation

schur_sles_param

cs_param_sles_t* schur_sles_param

strategy

strategy

Choice of strategy for solving the Navier–Stokes system
