    Hi, Ahmet. The best thing to do would be to use the 'initpoint' argument of your input dictionary and feed in a good initial guess to an equilibrium point. It looks like, based on your output, that you are at a limit cycle and not an equilibrium point. If your system is bistable, you can change initial conditions to see if you can't find an equilibrium point. You might have to change parameters to get this to occur. In any case, once you have computed a solution that settles to an equilibrium point,...

    Actually, just realized this is not PyCont related, so it's probably best if another member of the team chases after this one. Also just noticed that you are creating things symbolically, which I don't think VFGEN deals with. Anyone else from the PyDSTool team wanna try their hand at this?

    Hi, Ahmet. I'll take a look at your code, but in the meantime, you might want to try VFGEN by Weckesser. It's a markup language for differential equations models. What's nice about it is you only need to write up the model once, and then VFGEN can create XPPAUT and PyDSTOOL model files from the template. Pretty nice. I'll report back if I find where your model is having trouble.

    Yes, my apologies for being absent on this one - other job commitments kept me away...

    You can specify the initdirec argument of the continuer class, as a dictionary.
