[Trilinos-Users] [EXTERNAL] flatten a multivector?

[Salinger, Andrew]

Jeremy,

I think that what you are looking for is the Thyra ProductVector. This is an
abstract vector made up of sub-vectors, each with their own concrete
implementation.

Irina Tezaur has recently implemented something like this with Alejandro
Mota in Albany for MultiScale coupling. If you get a copy of Albany (github)
you can look for guidance in Albany/src/LCM/SchwarzMultiscale.cpp

Irina based this on working Trilinos code, such as in Teko (and perhaps Panzer
and Thyra examples). These may be better resources -  I just happen to know
where to point you for the Multiscale use case, with the benefit that the
developers are local to you in SNL-CA.

Subject: [EXTERNAL] [Trilinos-Users] flatten a multivector?

Hi there, I would like to flatten a multi vector such that if it has two columns it will construct a vector with one column which first contains column 1 followed by column 2 of the multi vector.  This would be handy to easily switch between segregated and monolithic solves.  Is there the capability to do this somewhere in Trilinos already?
Thanks,
Jeremy
