Detailed Description

Structure storing all metadata related to the resolution of a saddle-point linear system.

Field Documentation

◆ cvg_param

cvg_param

Structure storing the parameters to know if an iterative process has to stop (convergence or divergence). These criteria are related the iterative algorithm used to solve the saddle-point system. This is the case for instance with an Uzawa or GKB algorithm.

◆ precond

precond

Type of preconditioner for the saddle-point system which is viewed as a 2x2 block matrix.

◆ schur_approximation

schur_approximation

Choice of the way of preconditioning the schur approximation

◆ schur_sles_param

schur_sles_param

Set of paremeters used to solve the Schur complement if needed. This depends on the type of Schur approximation which has been cosen.

◆ solver

solver

Type of solver to solve the saddle-point system If solver is set to CS_PARAM_SADDLE_N_SOLVERS, then there is no need to solve a saddle-point system.

◆ verbosity

verbosity

verbosity (level of information displayed)
