Proposal : http://socghop.appspot.com/gsoc/student_proposal/private/google/gsoc2010/shrikanth/t127083559873

Mentor : [[Krishnan Chittur]]

==Goals==
ASCEND's thermophysical property database is presently available in files written using ASCEND syntax. This data is open and new data can added without any requirement of recompilation.But browsing data in difficult in this form. This Project aims at migrating present database in .a4l file to *.db format. SQLite can be employed for this database migration. Also it would be necessary to have certain interface to load database from an ASCEND model. After successful migration, tests are needed to formulated and carried out to make sure that the property formulations worked as expected.

==Work done==

Added 9 components into FPROPS database.

Patch for gibbs free energy in helmholtz function

==Present work==
====RADAU5====
Introduction

Radau5 codes are based on runge kutta implicit methods. The present native integrators LSODE and IDA are based on backward difference formula(BDF) where as newly added DOPRI5 and RADAU5 are based on single step methods of runge kutta are simply called march forward methods as they don't depend on previous values of y. RADAU5 codes are capable of integrating ''stiff ordinary differential equations'' and ''differential algebraic equations'' and there general accuracy of order 5. For further reading please refer ''Solving ordinary differential equations part 2 by E.Hairer and G.Wanner'' where solving procedure as well code are discussed.

===work done===

Primary wrapper for integrator is finished and is available in trunk version.

Integrator performance against van der pol problem (stiff ode) has been satisfactorily tested.

===Further work===

More rigorous testing required to be performed.

Present wrapper supports solving ODE's. Although DAE's can also be solved but approach doesn't make use of native ability of RADAU5 and order of accuracy would be smaller. Extending wrapper support to make use RADAU5's DAE solving ability is in proposed further work.

1)As of now to equate fugacities of liquid phase and gas phase for saturation boundaries.

2)Migrating database will be done in later phase

Rshrikanth: /* For ASCEND 0.9.7 with the Tcl/Tk GUI */

== For ASCEND 0.9.7 with the Python GUI ==

To be installed in this order:

* [http://www.python.org/ftp/python/2.6/python-2.6.msi Python 2.6] (be sure to install the 32-bit version)
* [http://ftp.gnome.org/pub/GNOME/binaries/win32/glade3/3.6/glade3-3.6.7-with-GTK+.exe Glade with GTK+ 3.6.7]
* [http://ftp.gnome.org/pub/GNOME/binaries/win32/pygobject/2.14/pygobject-2.14.2-2.win32-py2.6.exe PyGObject 2.14.2 py2.6]
* [http://ftp.gnome.org/pub/GNOME/binaries/win32/pycairo/1.4/pycairo-1.4.12-2.win32-py2.6.exe PyCairo 1.4.12-2 py2.6]
* [http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.16/pygtk-2.16.0.win32-py2.6.exe PyGTK 2.12.1-3 py2.6]

Optional components:

* [http://ipython.scipy.org/dist/0.10/ipython-0.10.win32-setup.exe IPython 0.10] (for console support)
* [http://sourceforge.net/projects/numpy/files/NumPy/1.3.0/numpy-1.3.0-win32-superpack-python2.6.exe/download NumPy 1.3.0] (to support Matplotlib)
* [http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.1/matplotlib-0.99.1.win-amd64-py2.6.exe Matplotlib 0.99.1] (for plotting and incidence matrices)

Backup copies of many of the above files are available from [http://www.eng.uah.edu/~kchittur/files4windows this site].

== For ASCEND 0.9.7 with the Tcl/Tk GUI ==

The ActiveState site has recently removed the Tcl/Tk installer that was required by ASCEND during installation. A copy of the original file is available from here:

* http://www.eng.uah.edu/~kchittur/files4windows/ActiveTcl8.4.15.0.280619-win32-ix86-threaded.exe

We also believe that the following release will work, but have not yet tested it:

* http://downloads.activestate.com/ActiveTcl/releases/8.4.19.3/ActiveTcl8.4.19.3.291941-win32-ix86-threaded.exe

== For ASCEND 0.9.6 with the PyGTK GUI ==
<div class="notice metadata" id="outdated" style="border:solid 2pt #FDB; width:70ex; background-color:#FFF8F4;padding:4px;margin-bottom:6px">''This section is '''outdated'''. You can help out by <span class="plainlinks">[http://ascendwiki.cheme.cmu.edu/index.php?title=Prerequisites_for_Windows&action=edit updating it]</span>. ''</div>
<div style="border:solid 2pt blue;padding:5px">ASCEND now supports Python 2.5. (See link to sourceforge.net download page below). If installing ASCEND with Python 2.5, be sure to get the <tt>-py2.5</tt> versions of the dependencies listed below. We have tested ASCEND with more up-to-date versions (than those listed here) of the GTK and PyGTK and related packages and that seems to work OK as well.</div>

First install Python [http://www.python.org/download/releases/2.4.4/ version '''2.4''']. We are not yet supporting Python 2.5 on Windows (although it is tested on Linux and should work).

Next install GTK+. Download the [http://downloads.sourceforge.net/gladewin32/gtk-win32-devel-2.6.10-rc1.exe gtk-win32-devel-2.6.10-rc1.exe] file from the [http://sourceforge.net/project/showfiles.php?group_id=98754&package_id=111411 gladewin32] project.

Next, install the following additional reqired python-related packages on your machine (easily located with Google):

* [http://ftp.gnome.org/pub/gnome/binaries/win32/pycairo/1.0/pycairo-1.0.2-1.win32-py2.4.exe pycairo-1.0.2-1.win32-py2.4.exe]
* [http://ftp.acc.umu.se/pub/gnome/binaries/win32/pygtk/2.6/pygtk-2.6.3-1.win32-py2.4.exe pygtk-2.6.3-1.win32-py2.4.exe]

You will require the following (for versions up to ASCEND 0.9.5.109, or they are optional for 0.9.5.110) for graphics support:

* [http://downloads.sourceforge.net/matplotlib/matplotlib-0.90.0.win32-py2.4.exe matplotlib-0.90.0.win32-py2.4.exe]
* [http://prdownloads.sourceforge.net/numpy/numpy-1.0.2.win32-py2.4.exe numpy-1.0.2.win32-py2.4.exe]

The remaining packages are optional. If you want to enable [[Python console support]] for scripting/debugging:

* [http://ipython.scipy.org/dist/ipython-0.8.0.win32.exe ipython-0.8.0.win32.exe]
* (another python extension module), which in turn requires
** [http://downloads.sourceforge.net/ctypes/ctypes-1.0.1.win32-py2.4.exe ctypes-1.0.1.win32-py2.4.exe] (note: this dep will drop off with Python 2.5 -- built-in)
** [http://ipython.scipy.org/dist/pyreadline-1.4.2.win32.exe pyreadline-1.4.2.win32.exe]
** [http://downloads.sourceforge.net/ctypes/ctypes-1.0.1.win32-py2.4.exe ctypes-1.0.1.win32-py2.4.exe] (note: this dep will drop off with Python 2.5 -- built-in)
** [http://ipython.scipy.org/dist/pyreadline-1.4.2.win32.exe pyreadline-1.4.2.win32.exe]
* [http://downloads.sourceforge.net/ctypes/ctypes-1.0.1.win32-py2.4.exe ctypes-1.0.1.win32-py2.4.exe] (note: this dep will drop off with Python 2.5 -- built-in)
* [http://ipython.scipy.org/dist/pyreadline-1.4.2.win32.exe pyreadline-1.4.2.win32.exe]

== For ASCEND 0.9.6 with the Tcl/Tk GUI ==

* Tcl/Tk 8.3 or [http://downloads.activestate.com/ActiveTcl/Windows/8.4.15/ActiveTcl8.4.15.0.280619-win32-ix86-threaded.exe 8.4 (ActiveState distribution)]
* TkTable 2.8 or 2.9 (link required here?)
* xgraph (optional)

== CONOPT ==

Optionally, if you want to use the [[CONOPT]] or [[CMSlv]] solvers, you will need CONOPT. We have a .exe installer that we can provide to registered users of CONOPT.
