Structure storing the parameters related to the resolution of the Navier-Stokes system.
| coupling |
Choice of algorithm for solving the system
| density |
Density of the fluid, pointer to cs_property_t used in several terms in the Navier-Stokes equations
| dof_reduction_mode |
How are defined the Degrees of freedom
| gd_scale_coef |
Default value to set the scaling of the grad-div term when an artificial compressibility algorithm or an Uzawa-Augmented Lagrangian method is used
| gravity |
Vector related to the gravity effect
| has_gravity |
Take into account the gravity effect: true or false
| lami_viscosity |
Laminar viscosity, pointer to cs_property_t associated to the diffusion term for the momentum equation
| max_algo_iter |
Maximal number of iteration of the coupling algorithm. Not useful for a monolithic approach. In this case, only the maximal number of iterations for the iterative solver is taken into account
| model |
Modelling related to the Navier-Stokes system of equations
| n_pressure_ic_defs |
Number of initial conditions associated to the pressure
| n_velocity_ic_defs |
Number of initial conditions associated to the velocity
| pressure_ic_defs |
Pointers to the definitions of the initial conditions associated to the pressure. In order to force a zero-mean pressure, the code can compute the average of the resulting pressure and subtract it
| pressure_ic_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t
| qtype |
A cs_quadrature_type_t indicating the type of quadrature to use in all routines involving quadratures
| residual_tolerance |
Tolerance at which the Navier–Stokes is resolved (apply to the residual of the coupling algorithm chosen to solve the Navier–Stokes system)
| space_scheme |
Discretization scheme for space
| theta |
Value of the parameter for the time scheme when a theta-scheme is used
| time_scheme |
Discretization scheme for time
| time_state |
Status of the time for the Navier-Stokes system of equations
| velocity_ic_defs |
Pointers to the definitions of the initial conditions associated to the velocity. The code does not check if the resulting initial velocity satisfies the divergence constraint.
| velocity_ic_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside the a cs_equation_param_t structure dedicated to the momentum equation.
| verbosity |
