Thermodynamics & Physical Properties

CAPE-OPEN focuses on uniform fluids that are mixtures of pure components or pseudo-components. The operations that have been provided with standardised interfaces are those required for the calculation of phase equilibria as well as other commonly used thermodynamic and transport properties. A key concept is that of a Material Object. Typically, each distinct material appearing in a process (in streams flowing between unit operations, as well as within individual unit operations) is characterized by one such object.

Focuses on the solution algorithms that are necessary for carrying out steady state and dynamic simulation of lumped systems: for the solution of large, sparse systems of non-linear algebraic equations (NLAEs) and mixed (ordinary) differential and algebraic equations (DAEs). Introduces new concepts: models and the equation set object (ESO), which is a software abstraction of a set of non-linear algebraic or mixed (ordinary) differential and algebraic equations.
