After about a year's design and coding, now a advanced version of Solucalc has been developed. The advanced version is called ISLEC, which used a Particle swarm based Gibbs free energy minimization approach to solve the equilibrium problem. At the same time, the Pitzer's model proposed by C. E. Harvie & J. Weare in 1980 was persisted.
ISLEC has many features:
1. Single point calculation was used instead of line calculation
2. Database was used instead of putting all the parameters...
