I think there are several ways to interpret the situation/problem you could be having from the description you gave. You would do well to provide a concise example of what you are talking about.

I want to keep some of the variables (the parameters in the differential equations) constant during the simulation. Right now, I have to look for the first derivative of every variable in a sea of differential equations and set it to zero. Is there a more "elegant" way to do this in mathematica? > > -- http://chris.chiasson.name/
