ASCEND

ASCEND Modelling Environment

ASCEND is a free and open source software for mathematical modeling. It is a initiative of Carnegie Mellon University and it started on late 1980's. ASCEND solves models by equation based approach thus greatly emphasizing on knowledge of model rather than procedural coding. Till date ASCEND has been widely employed in simulating chemical process models but it can also be used for general purpose modeling and simulation.

Installation Procedure

Installation on windows system

Latest Version of ASCEND can be downloaded from http://sourceforge.net/projects/ascend-sim/files/. In a proxy free environment, installer will search for installed prerequisite files first then installs missing prerequisite files and ASCEND. Alternatively for users who are using Internet behind proxy server or don't have Internet connection, they can manually install following files in the same order as shown. After installing these prerequisite files installer can be executed to install ASCEND into system.

Prerequisite Files:

• Python 2.6 (be sure to install the 32-bit version)
• Glade with GTK+ 3.6.7
• PyGObject 2.14.2 py2.6
• PyCairo 1.4.12-2 py2.6
• PyGTK 2.12.1-3 py2.6

Backup copies of these files are available from http://www.eng.uah.edu/~kchittur/files4windows this site.

Optional components:

• IPython 0.10 (for console support)
• NumPy 1.3.0 (to support Matplotlib)
• Matplotlib 0.99.1 (for plotting and incidence matrices)

Notes:

• ASCEND is not compatible with Windows Vista and Windows 7.
• Recommended version is Windows XP.
• Above installation procedure is for pygtk environment. Since support for older TCL/TK environment is not available, the procedure for Tcl/Tk version of ASCEND has been skipped here.

MAC

Currently installer is not available for Mac machines, but ASCEND runs perfectly on mac after building it from source.
