Function Documentation

◆ cs_user_physical_properties()

void cs_user_physical_properties ( cs_domain_t *  domain)

Function called at each time step to define physical properties.

This function is called each time step to define physical properties.

Parameters
[in,out]domainpointer to a cs_domain_t structure

◆ cs_user_physical_properties_h_to_t()

void cs_user_physical_properties_h_to_t ( cs_domain_t *  domain,
const cs_zone_t *  z,
bool  z_local,
const cs_real_t  h[],
cs_real_t  t[] 
)

User definition of enthalpy to temperature conversion.

This allows overwriting the solver defaults if necessary.

This function may be called on a per-zone basis, so as to allow different conversion relations in zones representing solids or different fluids.

Parameters
[in,out]domainpointer to a cs_domain_t structure
[in]zzone (volume or boundary) applying to current call
[in]z_localif true, h and t arrays are defined in a compact (contiguous) manner for this zone only; if false, h and t are defined on the zone's parent location (usually all cells or boundary faces)
[in]henthalpy values
[in,out]ttemperature values

◆ cs_user_physical_properties_t_to_h()

void cs_user_physical_properties_t_to_h ( cs_domain_t *  domain,
const cs_zone_t *  z,
bool  z_local,
const cs_real_t  t[],
cs_real_t  h[] 
)

User definition of temperature to enthalpy conversion.

This allows overwriting the solver defaults if necessary.

This function may be called on a per-zone basis, so as to allow different conversion relations in zones representing solids or different fluids.

Parameters
[in,out]domainpointer to a cs_domain_t structure
[in]zzone (volume or boundary) applying to current call
[in]z_localif true, h and t arrays are defined in a compact (contiguous) manner for this zone only; if false, h and t are defined on the zone's parent location (usually all cells or boundary faces)
[in]htemperature values
[in,out]tenthalpy values

◆ cs_user_physical_properties_td_pressure()

void cs_user_physical_properties_td_pressure ( cs_real_t *  td_p)

User function to define a custom law for the thermodynamic pressure.

Allows to define a custom law for the constant uniform thermodynamic pressure (whenn cs_velocity_pressure_model_t::idilat = 3 or cs_fluid_properties_t::ipthrm = 1).

The density is then updated (in cs_compute_thermo_pressure_density.c) as:

\[\rho^{n+1} =\rho^{n} \cdot \frac{P_{th}^{n+1}}{P_{th}^{n}}\]

.

Parameters
[in,out]td_pUpdated value of the thermodynamic pressure

◆ cs_user_physical_properties_turb_viscosity()

void cs_user_physical_properties_turb_viscosity ( cs_domain_t *  domain)

User modification of the turbulence viscosity.

Turbulent viscosity $ \mu_T $ (kg/(m s)) can be modified. You can access the field by its name.

Parameters
[in,out]domainpointer to a cs_domain_t structure
