D1mix_constant Subroutine

public subroutine D1mix_constant(self, n, d1i, D1, dD1i, dD1ij)

Constant $\delta_1$ parameter.

Most Cubic EoS keep a constant value for their $\delta_1$ parameter. This procedure assumes that all the components have the same $delta_1$ and takes the first value as the one of the mixture.
