I was implicitly referring to Python/C model for this.
I'm aware that Python can be very slow on heavy computations (it's a
_documented_ shortcoming), sometimes much slower than Simulink.
I believe that no current technology can meet the needs of both rapid

Ok no problem. Let me just a few days to strip any irrelevant data on
it...

In your simulator how much do you want Python to do? I ask this
because your subject title implies you want to write your simulation
code in Python but a simulator written entirely in Python would be
very slow. Python is an interpreted language and pure Python code is
not suitable for
Hello Phil,
I'm currently looking to see if I can build upon SimPy, thus making it
an hybrid system simulator. That would be a great step for the
community.
Main difficulty would be to build a framework which isn't clumsy, like
you said.
I have close to no experience in Python and object
I don't know much about numerical aerodynamics, but assume that you are
interested in a finite element solver. I googled a bit and found the
following projects. The first is a 2d finite element solver for python.
The second is a 2d finite element solver without python.

Simulink is a framework widely used by the control engineers ...
It is not *perfect* but the ODEs piece is probably the best
part of the simulator. Why were you not convinced ?
You may also have a look at Scicos and Ptolemy II. These
simulators are open-source ... but not based on Python.
Simulink is well fitted for small simulators, but when you run into big
projects, I find many shortcomings appears which made the whole thing
next to unusable for our kind of projects.
That's why I'm interested in Python by the way, it is not a simple clone
like Scilab/Scicos. It is a real
Nicholas,
I have a particular interest in this subject as well. I've also used
the Python/Scipy combination, and it is a tantalizing combination, but
I found it to be a bit more clumsy than I'd like. Plus, my need for
continuous-time simulation is not as great as it has been in the past.

Have you looked at Octave? It is not Python, but I believe it can talk
to Python.
Octave is comparable to Matlab for many things, including having ODE
solvers. I have successfully used it to model and simulate simple
systems. Complex system would be easy to model as well, provided that
Hello Phil,
Yes I have considered Octave. In fact I'm already using Matlab and
decided to 'reject' it for Python + Numeric/numarray + SciPy because I
think you could do more in Python and in more simple ways.
Problem is that neither Octave, Matlab and Python offer today a
framework to build
