Simbiology: How to use a species calculated by a repeated rule in downstream reactions

Hi,

I have a species that is calculated by a repeated assignment rule. I need to use this species as a reactant in a different (reversible) reaction elsewhere in the model, e.g:

B = repeated assignment rule

C = kf*A*B - kr*C

However, when simulating the model Simbiology throws an error that B is over determined because it's being varied elsewhere in the model.

Is it possible to use species calculated by rules in downstream reactions, or is there a different strategy for making this kind of species available for other calculations? (I'm guessing probably not due to the very nature of repeated assignment rules but hoping somebody has a clever hack!)

Thanks for any help.

Hi,

If you don't want a species to be modified by reactions that it participates in, you need to set the BoundaryCondition property to true. You can get more information about that here.
