COEFF_dt_free
(experimental) factor for exaggerated movement of the free surface (UCV)
COEFF_dt_free = 3.0
Default: COEFF_dt_free = 1.0
In the example above, the free surface travels three times as fast as given by the velocity.
if COEFF_dt_free < 0 , then the free surface is not moved in minimal way, but it is moved in LAGRANGE sense. The inner points (%BND_none% or %IDENT_none% ) are moved accordingly in the EULER / EULERIMPL sense .
Note: This parameter was introduced for faster finding of the steady state of a flow in conjunction with EULER or EULERIMPL .
For LAGRANGE, it does not make sense to use it and is, thus, inactive
