Most Commonly Used Calculation Methods
These methods may be used for a wide variety of simulations, although no method is optimal for every application. The methods listed here are grouped by industry. The name for each system is derived from the Equilibrium K-value method. The table lists the methods used (by default) for five basic properties.
