MFloat FvCartesianSolver::m_cflViscous

Quasi-Courant number C_vis - Factor of the viscous "CFL condition"
The time-step restriction for the stability of an explicity Euler-forward step for the diffusion equation is $\Delta t <= C_{vis} \frac{\Delta x^2}{\nu}$ where $C_{vis} \in (0, 1/4]. For the Enthalpy solver $\nu$ is the diffusion coefficient, that is, the thermal diffusivity. For compressible-flow at constant Prandtl' number $\nu$ is the specific viscosity. Note that the unsteady diffusion equation is a parabolic problem, and although explicit schemes can be used to solve it stably, the restriction on the time-step increases with the square of the mesh size, so refining the grid makes the number of time-steps required to solve the problem explode.

\sigma \) is the forcing amplitude, \( x_{sp} \) is the inner sponge layer boundary, \( L_{sp} \) is the sponge layer thickness and \( \Delta \phi = \phi - \phi_{target} \) is the difference between the local and the freesteam values of \( \phi \).
The density target value is in these cases given as:
deltaRho =a_pvariable( cellId , PV->RHO ) - m_rhoInfinity * m_targetDensityFactor;
