public class SystemSrkCPAstatoilFullyImplicit
extends SystemSrkCPAstatoil

Thermodynamic system using the fully implicit CPA-EOS algorithm.

Uses the fully implicit algorithm from Igben et al. (2026) for simultaneous solution of molar volume and association site fractions. Falls back to standard nested approach if the implicit solver does not converge.
