◆ rvarfl

double precision, dimension(nscamx), save rvarfl

When iscavr(iscal)>0, rvarfl is the coefficient in the dissipation term $\-\frac{\rho}{R_f}\frac{\varepsilon}{k}$ of the equation concerning the scalar, which represents the root mean square of the fluctuations of the scalar.
Useful if and only if there is 1 $\leqslant$ iscal $\leqslant$ nscal such as iscavr(iscal)>0.

◆ visls0

double precision, dimension(nscamx), save visls0

reference molecular diffusivity related to the scalar J ( $kg.m^{-1}.s^{-1}$ ).

Negative value: not initialised
Useful if 1 $\leqslant$ J $\leqslant$ nscal, unless the user specifies the molecular diffusivity in the appropriate user subroutine (cs_user_physical_properties for the standard physics) (field_get_key_id (ivarfl(isca(iscal)),kivisl,...) -1)
Warning: visls0 corresponds to the diffusivity. For the temperature, it is therefore defined as $\lambda/C_p$ where $\lambda$ and are the conductivity and specific heat. When using the Graphical Interface, $\lambda$ and are specified separately, and visls0 is calculated automatically.
With the compressible module, visls0 (given in uscfx2) is directly the thermal conductivity $W.m^{-1}.K^{-1}$ .
With gas or coal combustion, the molecular diffusivity of the enthalpy ( $kg.m^{-1}.s^{-1}$ ) must be specified by the user in the variable diftl0(cs_user_combustion).
With the electric module, for the Joule effect, the diffusivity is specified by the user in cs_user_physical_properties.c (even if it is constant). For the electric arcs, it is calculated from the thermochemical data file.
