As I recall, it is hard to get Aztec to accept a new right hand side without having it recompute the setup phase. However, it’s been 20 years since I last used it.
AztecOO works very similarly and permits separation of the setup from the solve.

Subject: [Trilinos-Users] How to solve Ax=bs with many righ hand sides vector.
I use Aztec to solve Ax=b for my CFD problem. and the matrix A is fixed, but vector b may change values. So i want to know how to solve Ax=bs with many righ hand sides in one turn.
