We have the following situation (briefly):
Soem time ago, we were provided with a version of a model and have carried out some work on parts of it, including the addition of growth/creep. We have now recieved an updated version of the "base" model and need to combine the changes in the two versions of the model.
What's the best way of doing this? I'm concerned that the same things (e.g. contributing area surfaces) may have been changed in both models.
