[Trilinos-Users] Mesh and DOF management with trilinos

[Dharmendar Reddy]

Hello Andrew,
                       Just went through the slides at
https://trilinos.org/oldsite/events/trilinos_user_group_2011/presentations/PawlowskiCyr_TUG_Panzer_2011_10_v3.pdf
Looks cool to me. I would like to give it a shot. Is there an example code
?

I am trying to setup a code for quantum transport simulation in
semiconductor device.


Thanks
Reddy
