[Trilinos-Users] [EXTERNAL] NOX using direct solver MUMPS

Hi Simon,

In regards to question #1, Amesos can be used by NOX via the stratimikos 
interface to linear solvers.  NOX uses the stratimikos interface in both 
the src-thyra and src-epetra (NOX_Epetra_LinearSystem_Stratimikos.H) 
layers.  You could use either to get access to Amesos/MUMPS in NOX.  
There are no concrete examples using Amesos in NOX, but it should work.
