This project is not part of the GNU Project.

With Model Builder you can easily enter your own system of ODE(s) in a simple syntax (actually Python) as well as values or expressions for parameters.

The System is integrated numerically using the LSODE package which can handle stiff (BDF method) or non-stiff (adams method) systems, and displays a time plot of the results at the end of the intergration. The   program can also display a tabular output of the results.

The equations may be non-autonomous, and may contain stochastic terms. The solver uses variable step sizes and adjusts the order of the integration method automatically at each step.

Model Builder also has a module for Bayesian uncertainty analysis.

The program requires Python, wxPython 2.4, NumPy, Scipy, Rpy and matplotlib to run.

Development has accelerated over the past few months.

The next release is almost ready. Due to the considerable number of new features, It will still take a while until everything is tested, and the system as a whole works.

A glimpse into the new features: ...

Coming Up: Uncertainty analysis
     posted by fccoelho, Tue 29 Apr 2003 02:14:20 PM UTC - 0 replies

I am finishing an Uncertainty analysis tool for Model Builder that will be out on the next major release, meanwhile CVS users will be able to use in the preliminary stages.

The next Major release will probably contain a Sensitivity analysis mode as well.

If I didn't have to teach so many classes I would be able to spit out feature full releases, way more often!!


equation box font bug squished!
