Structure storing additional elements associated with the usage of the Algebraic Fractional Step methods (AFS) including SIMPLE-like algorithm.
| bool dedicated_init_sles |
| init_sles_param |
The initial linear system requires a more accurate resolution. Thus, one adds a dedicated cs_param_sles_t structure for this purpose)
| scaling_coef |
The scaling_coef used in the lumped inversion if (1,1)-block matrix such as to solve the A.x = 1/scaling_coef. By default the value is 1.0. scaling_coef < 1 corresponds to an under-relaxation on the pressure.
| xtra_sles_param |
Set of parameters only used in some situations such as the need to solve approximately the A.x = 1 linear system (A is the (1,1)-block matrix). This is a complementary step in the approximation of the Schur complement.
By default, this is a copy of the block11_sles_param with less restrictive convergence criteria
