Since in this case the growth equation is a stiff o.d.e, it is integrated in time using the Rosenbrock method (see Numerical Recipes in FORTRAN, 2nd Edition, p.731). If the droplet radius is larger or equal ''1.0E-6'' m, solution and curvature effects are neglected and the growth is calculated by a simple analytic formula (as for '''curvature_solution_effects''' = ''.F.'').\\\\ |
