BoundaryConditions

BoundaryConditions
is a list attribute containing species in the model whose time derivatives are set to zero.
EXAMPLESCLOSE ALL
Basic Examples   (1)
Access the boundary conditions of a model
The differential equations of h2oc
Set new boundary conditions for model (discard old ones)
Now the time derivative of h2oc[t] is set to zero
Updating the parameters will add to the already existing parameters. Newly defined parameters take precedence over already existing ones.
Now the time derivates of both h2oc[t] and hc[t] are set to zero.
