CS_NAVSTO_N_MODELS

◆ cs_navsto_param_sles_t

enum cs_navsto_param_sles_t

High-level information about the way of settings the SLES for solving the Navier-Stokes system. When a the system is treated as a saddle-point problem (monolithic approach in what follows), then one uses these notations: A_{00} is the upper-left block and A_{11} (should be 0 but the preconditionner may have entries for the approximation of the inverse of the Schur complement).

Enumerator
CS_NAVSTO_SLES_EQ_WITHOUT_BLOCK	Associated keyword: "no_block" Use the same mechanism as for a stand-alone equation. In this case, the setting relies on the function cs_equation_set_sles and the different options for solving a linear system such as the choice of the iterative solver or the choice of the preconditionner or the type of residual normalization
CS_NAVSTO_SLES_BLOCK_MULTIGRID_CG	Associated keyword: "block_amg_cg" The Navier-Stokes system of equations is solved using a multigrid on each diagonal block as a preconditioner and applying a conjugate gradient as solver. Use this strategy when the saddle-point problem has been reformulated into a "classical" linear system. For instance when a Uzawa or an Artificial Compressibility coupling algorithm is used. (i.e. with the parameter CS_NAVSTO_COUPLING_ARTIFICIAL_COMPRESSIBILITY or CS_NAVSTO_COUPLING_UZAWA is set as coupling algorithm). This option is only available with the support to the PETSc library up to now.
CS_NAVSTO_SLES_ADDITIVE_GMRES_BY_BLOCK	Associated keyword: "additive_gmres" Available choice when a monolithic approach is used (i.e. with the parameter CS_NAVSTO_COUPLING_MONOLITHIC is set as coupling algorithm) The Navier-Stokes system of equations is solved an additive preconditioner (block diagonal matrix where the block 00 is A_{00} preconditionned by one multigrid iteration and the block 11 is set to the identity. This option is only available with the support to the PETSc library up to now.
CS_NAVSTO_SLES_DIAG_SCHUR_GMRES	Associated keyword: "diag_schur_gmres" Available choice when a monolithic approach is used (i.e. with the parameter CS_NAVSTO_COUPLING_MONOLITHIC is set as coupling algorithm). The Navier-Stokes system of equations is solved using a block diagonal preconditioner where the block 00 is A_{00} preconditioned with one multigrid iteration and the block 11 is an approximation of the Schur complement preconditionned with one multigrid iteration. The main iterative solver is a flexible GMRES. This option is only available with the support to the PETSc library up to now.
CS_NAVSTO_SLES_UPPER_SCHUR_GMRES	Associated keyword: "upper_schur_gmres" Available choice when a monolithic approach is used (i.e. with the parameter CS_NAVSTO_COUPLING_MONOLITHIC is set as coupling algorithm). The Navier-Stokes system of equations is solved using a upper triangular block preconditioner where the block 00 is A_{00} preconditioned with one multigrid iteration and the block 11 is an approximation of the Schur complement preconditionned with a minres. The main iterative solver is a flexible GMRES. This option is only available with the support to the PETSc library up to now.
CS_NAVSTO_SLES_GKB_GMRES	Associated keyword: "gkb_gmres" Available choice when a monolithic approach is used (i.e. with the parameter CS_NAVSTO_COUPLING_MONOLITHIC is set as coupling algorithm). The Navier-Stokes system of equations is solved using a Golub-Kahan bi-diagonalization (GKB) as preconditionner of a flexible GMRES solver. The GKB algorithm is solved with a reduced tolerance as well as the CG+Multigrid used as an inner solver in the GKB algorithm. One assumes that the saddle-point system is symmetric. The residual for the GKB part is computed in the energy norm. This option is only available with the support to the PETSc library up to now.
CS_NAVSTO_SLES_GKB	Associated keyword: "gkb" Available choice when a monolithic approach is used (i.e. with the parameter CS_NAVSTO_COUPLING_MONOLITHIC is set as coupling algorithm). The Navier-Stokes system of equations is solved using a Golub-Kahan bi-diagonalization. One assumes that the saddle-point system is symmetric. By default, the block A_{00} may be augmented (this is not the default choice) and is solved with a conjuguate gradient algorithm preconditionned with a multigrid. The residual is computed in the energy norm. This option is only available with the support to the PETSc library up to now.
