◆ has_gravity

has_gravity

Take into account the gravity effect: true or false

◆ lami_viscosity

lami_viscosity

Laminar viscosity, pointer to cs_property_t associated to the diffusion term for the momentum equation

◆ max_algo_iter

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

model

Modelling related to the Navier-Stokes system of equations

◆ n_pressure_bc_defs

n_pressure_bc_defs

Number of boundary conditions associated to the pressure field.

◆ n_pressure_ic_defs

n_pressure_ic_defs

Number of initial conditions associated to the pressure

◆ n_velocity_bc_defs

n_velocity_bc_defs

Number of definitions related to the settings of the boundary conditions for the velocity field.

◆ n_velocity_ic_defs

n_velocity_ic_defs

Number of initial conditions associated to the velocity

◆ pressure_bc_defs

pressure_bc_defs

Pointers to the definitions of the boundary conditions associated to the pressure field.

◆ pressure_bc_is_owner

pressure_bc_is_owner

True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t if an equation solves the pressure field.

◆ pressure_ic_defs

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

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

qtype

A cs_quadrature_type_t indicating the type of quadrature to use in all routines involving quadratures

◆ residual_tolerance

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)

◆ sles_strategy

sles_strategy

Choice of strategy for solving the SLES system

◆ space_scheme

Discretization scheme for time

◆ time_state

time_state

Status of the time for the Navier-Stokes system of equations

◆ velocity_bc_defs

velocity_bc_defs

Array of pointers to the definition of boundary conditions for the velocity field

◆ velocity_bc_is_owner

velocity_bc_is_owner

True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t Most of the time this should be false since an equation is associated to to the resolution of the velocity field (the momentum equation).

◆ velocity_ic_defs

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

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

verbosity

Level of display of the information related to the Navier-Stokes system
