	)

Compute the diffusion velocity at faces.

Compute the diffusion velocity at faces. i_visc,b_visc = viscosity*surface/distance, homogeneous to a rate of flow in kg/s.

i_visc,b_visc = viscosity*surface/distance, homogeneous to a rate of flow in kg/s.

Please refer to the viscfa section of the theory guide for more informations.

Remarks

: a priori, no need of reconstruction techniques (to improve if necessary).
