Hi all,
for the reanalysis of a set of problems (think sensitivity study, reliability, ... ), I'd like to reuse (some) of the search directions of previous problems I solved. The idea is to orthogonolize the new search directions also to a set of user-defined vectors. This idea is not new, and while browsing through the mailing lists, there have been a few discussions on related topics. 1* Can I access/store the old search directions of an iterative solve. Maybe through KSP? 2* Is there an augmented conjugated gradient implementation available? I've read some discussions on whether or not to implement this since a multigrid approach can reach the same objective. But I don't know if it was implemented or not. thanks, Vincent
