Matlab CAPE-OPEN Thermo Import
This Matlab package allows for importing CAPE-OPEN version 1.1 thermodynamic and physical Property Packages into Matlab. A command driven package allows for selecting a CAPE-OPEN Property Package, and then perform thermodynamic and physical property calculations as well as thermodynamic equilibrium calculations inside Matlab.
The package defines the interfaces to communicate with CAPE-OPEN thermodynamic and physical Property Packages; it does not implement the thermodynamic engine itself. To use this package, you will need to have Matlab (version 5.3 or higher) as well as a CAPE-OPEN version 1.1 compliant thermo system installed (for example, TEA which is shipped with the freely available CAPE-OPEN simulation environment COCO Simulator).
To get started with the Matlab CAPE-OPEN thermo import, type help capeOpen in Matlab after installation.
An example:
» handle=capeOpenGetPackage('TEA (CAPE-OPEN 1.1)','C1_C2');
» %let's calculate and plot the phase envelope at 1 atm for this system
» frac=0:0.05:1;
» X=[frac' 1-frac']
X =

0.0500 0.9500
0.1000 0.9000

Requirements
Matlab CAPE-OPEN Thermo Import will function with CAPE-OPEN version 1.1 compliant thermodynamic Property Package Managers and stand-alone Property Packages.
Matlab version 5.3 or higher must be installed and running at your system. Matlab CAPE-OPEN Thermo Import has been tested with Matlab versions 5.3, 6.1, 7.7 and 7.8

Notes on the Matlab path
The RegisterWithMatlab.exe utility will add the appropriate statements to the Matlab pathdef.m file for the CAPE-OPEN Thermo Import libraries to be loaded properly. This utility will modify C:\Program Files\Matlab\<version>\toolbox\local\pathdef.m file by default. To this it will add the C:\Program Files\AmsterCHEM\Matlab CAPE-OPEN Thermo Import\ and it subfolder DLL or MEXW32, depending on the Matlab version.
For Windows Vista and later, a virtual store copy of pathdef.m may exist, e.g. C:\Users\<myname>\AppData\Local\VirtualStore\Program Files\MATLAB\<version>\toolbox\local\pathdef.m. In this case, the modifications made to the system copy will not affect Matlab's path and it will appear as if the path registration has failed. This situation will only occur on systems on which the user has edited the pathdef.m file.
To resolve this situation, please manually copy the added lines from the system copy of pathdef.m to the user copy.
Change log
Version 1.0.3
- fixed sizes of return values of phase fractions and phase compositions of capeOpenEquilibrium
Version 1.0.4
- calling put_simulationContext after rather than before Initialize
- fixed call to Terminate for Property Packages
Version 1.0.5
- corrected GetEquilibriumProp in case all no properties are to be calculated; old property list was used (answers were correct, but warnings were produced)
- corrected availability of pressure derivatives of single- and two-phase properties
