Class ColumnSolverFactory

java.lang.Object

neqsim.process.equipment.distillation.ColumnSolverFactory

final class ColumnSolverFactory
extends Object

Factory for the built-in distillation column solver strategies.

This class keeps enum dispatch outside DistillationColumn. The first implementation is a thin adapter layer around the existing numerical methods so that the public behavior remains unchanged while future rigorous solvers can be added as separate strategies.
