Dear Robert,
I not being able to exercise the PyCont_vanDerPol.py example
I am under OpenSUSE linux (64bit). Python 2.6.2, Numpy 1.5.1, Scipy
0.8.0, Swig 1.3.36, gcc 4.5
I initially had some problems to run the Dopri, Radau and PyCont examples.
Problems went away after removing the -m32 (on Generators and ContClass)
and installing the development package for Numpy (otherwise it complains
about Numarray headers).
There is also a TK backed problem with my Matplotlib on SLIP_2D_maps.py.
I will look into more detail.
This is the vanDerPol problem (error messages):
======================
> python PyCont_vanDerPol.py
....
UD1: Integrating backward...
Found initial point on curve.
Beginning continuation...
...
Lost canard!
Error: <type 'exceptions.KeyError'> : message: 'UD'
done!
....
UD1: Integrating forward...
Found initial point on curve.
Beginning continuation...
Lost canard!
done!
Traceback (most recent call last):
File "PyCont_vanDerPol.py", line 368, in <module>
plot_cycles(C, 'UD1')
File "PyCont_vanDerPol.py", line 274, in plot_cycles
if pt.labels['UD']['data'].has_key('cycle'):
KeyError: 'UD'
========================
Any idea of how can I fix it?
What is the current development status of the PyDSTool? I see you still
commit changes to the code and reply to the list/forum. Are there other
developers/daily users?
Where can I find more documentation besides the code?
I saw a thread on Gmane regarding the solvers and integration on Scipy.
Are there any advances on this direction?
What about collaborating with Sage?
I am asking all this questions because I am really interested on
learning / using PyDSTool to study nonlinear dynamical systems. I
recently started a PhD related to nonlinear micro electromechanical
systems and I am looking for tools and solvers to model and simulate
such devices.
Best regards,
Guilherme Torri
