Hi Tobias, Access to adjoints is interesting for more of us. We have not been able to prioritise it, but getting adjoint output is quickly moving up the list. However, I would be most interested in seeing the functionality in our most capable simulator, which today is flow (found within the opm

Hi, I'd just like to add that I think it makes a lot of sense to experiment in a less complex setting first, before adding these capabilities to Flow. Also, since we are going to refactor the Flow code to enable easier extension it may be a moving target for a while. In the long term, I definite

That sounds reasonable, it also seems to me that this might be the best place to start implementing the adjoints since the linearized residuals are already implemented. On 20 April 2015 at 09:05, Alf Birger Rustad wrote: > Hi Tobias, > > Access to adjoints is interesting for more of us. We have
