Re: [Ecell-users] A question about Python Process

[Koichi T. <sh...@sf...>]

PassiveStepper does nothing unless it is interrupted
by another Stepper.  Therefore, a model with only
a PassiveStepper does nothing, too.   You can use
DiscreteTimeStepper to check if your process is working
correctly, and then add the main part of the model
with ODEStepper or DiscreteEventStepper, and connect
it to PassiveStepper, if necessary.
