public class SystemSrkCPAstatoilReduced
extends SystemSrkCPAstatoil

Thermodynamic system using the reduced-dimension CPA-EOS solver with Broyden acceleration.

Combines association site symmetry reduction (grouping equivalent sites by charge pattern) with Broyden rank-1 inverse-Jacobian updates for compounded speedup. For systems with high site symmetry (e.g., water + MEG, both 4C), the coupled Newton system is reduced from (n_s+1) to (p+1) dimensions where p is the number of unique site types.
