[Trilinos-Users] ML, Maxwell's eq., higher order

[Jonathan Hu]

Dear Delia,

     The preconditioner in ML for Maxwell's equations is intended for 
1st order edge element discretizations.   It can (and has) been used in 
the context of a block preconditioner for higher order 
discretizations.   In particular, Peter Arbenz and his collaborators 
have used ML to precondition the portion of the linear system 
corresponding to the first order elements, and a lighter weight 
preconditioner for the higher order part.   Some of the details are in 
this report:  http://www.inf.ethz.ch/~arbenz/para04.pdf.  Please let me 
know if this of help to you.

Regards,
Jonathan
