The setting of each block relies on the cs_equation_param_t structure. The cs_equation_param_t structures related to the diagonal blocks are shared with the cs_equation_t structures in the "equations" member and thus not owned by the current structure. The extra-diagonal blocks dealing with the crossed terms (i.e. the coupling between variables) are owned by this structure. By default, there is no crossed term (i.e. params[1] = NULL) The same rationale applies to builder structures and scheme context structures. All these structures are contained in the structure cs_equation_core_t to avoid manipulating void ** structures | |

Main structure to handle a set of coupled equations.
| block_factories |
Matrix of cs_equation_core_t structures. The size of the matrix is n_equations (stored as an array of size n_equations^2). These structures enable to build and solve the system of equations.
| context |
pointer to a structure cast on-the-fly which depends on the numerical scheme
| define |
Initialize builder and scheme context structures. Pointer of function given by the prototype cs_equation_system_init_structures_t
| equations |
Array of pointer to the equations constituting the coupled system. These equations correspond to the each row and the cs_equation_param_t associated to an equation corresponds to the setting of the diagonal block.
| free |
Free builder and scheme context structures. Pointer of function given by the prototype cs_equation_system_free_context_t
| n_equations |
Number of coupled equations (> 1) composing the system
| param |
Set of parameters to specify the settings of the system of equations
| solve_steady_state_system |
Solve the system of equations (steady-state case). Pointer of function given by the generic prototype cs_equation_system_solve_t
| solve_system |
Solve the system of equations (unsteady case). Pointer of function given by the generic prototype cs_equation_system_solve_t
| system_helper |
Set of structures to define the system of equations (rhs, matrix or matrices, range sets, interface sets, etc.)
| cs_timer_counter_t timer |
Cumulated elapsed time
| int timer_id |
Id of the timer statistics
