Thermodynamic System
Use this window to select the default global thermodynamic system to be used in all the simulation problems. You can override this default method in an individual problem using the Thermodynamics Main Window.
Usage
From the Options / Simulation Defaults menu choose the "Global Thermodynamic System" item to display this window.
PRO/II provides numerous thermodynamic systems for your convenience. Furthermore, they are grouped into logical categories to facilitate location of the appropriate system(s) for solution of a flowsheet problem.
Select the Category to which the desired thermodynamic system belongs. The Primary Method list box is then filled with all the systems, which belong to the selected category. Select the desired method from this list box to specify it to be the global default thermodynamic method.
PRO/II provides various categories to apply thermo options at global level. Select any category from the list box and then select the default thermo options for all new problems based on the selected category. Select a method for Water Partial Pressure, Solubility, and Properties to specify these options to be the global default water options. Similarly, you can specify other Thermo options to be the global default Thermo options.
Global Thermodynamic System
Select the Global Thermodynamic Reset Option to transfer the thermodynamic between systems. When user will create a new flowsheet it will be created with selected Global Thermodynamic Reset Option. When nothing is selected new flowsheet will be created with Automatic reset option.
