Simulis Thermodynamics, while primarily a thermodynamic server, is also a Process Modelling Environment since a CAPE-OPEN Property Package can be plugged into it and calculations using that Property Package can be conducted within Simulis Thermodynamics.
Calculations can be requested for thermodynamic properties (enthalpy, viscosity, etc…) at a given point or for a range of conditions, resulting in plots being automatically generated. Same for phase equilibrium calculations.
