Model Reconstruction after Modification to Model Objects

[Pa Hari Krishna Achuthan]

Greetings All,

Im trying to model a two stage iterative model where i am conditionally adding scenarios to the first stage in an iterative model. The scenarios themselves are added in to the first stage as an addition of an element to a set, for e.g., using:

model.SetA.add(3)

However i recently saw that the reconstruct() method was deprecated. I have a lot of dependent variables, parameters and constraints defined using SetA. How do i effectively reconstruct and solve the model? The simple addition alone does not reflect the changes and create new objects for the variables, parameters and constraints.

Im using Pyomo version 6.9.1.
