Compute the recoil pressure p_v(T) in terms of the temperature T

                     /       /  1       1  \\

p_v(T) = s * c_p * exp|-c_T * | — - — || \ \ T T_v //

with a scaling factor s (0<=s<=1), the recoil pressure constant c_p, the temperature constant c_T and the boiling temperature T_v.

The scaling factor is introduced to potentially smoothly activate the recoil pressure and avoid a sharp activation. It is computed depending on the activation temperature T_ac of the recoil pressure

s = | -----— if T_ac < T < T_v | T_v - T_ac | | 1 if T >= T_v

• whereas the T_ac<=T_v.
