There is also the panzer library. In particular, the DOFManager global unknown numbering tool in panzer works with intrepid and allows low order grad, edge and curl basis functions. The doxygen for panzer is currently broken, but the DOFManager file itself has some documentation.

Thanks for the example. Looks like what i need. Is there a  documentation for STK  and seacas ? The doxygen links on trilinos website do not work for stk.

You can use STK for reading the mesh (it is very convenient with the new STK Ioss interface from SEACAS) and then use Epetra/Tpetra maps. This is presented in the following example

There is also a FE assembly with Intrepid (which is compatible to Intrepid2) in the example if you plan to use that.

Hello All,
               I am planing to switch my code from Fortran+petsc to
C++ and trilinos. I have an FEM code which uses petsc DMPlex
(http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/DM/DMPLEX.html)


Is there anything similar to DMPlex object in any of the trilinos
packages which can help me manage the mesh, DOF, setup and assembly of
the operators.

I would like to readin a mesh in exodus format into the mesh handler
and then use to help setup the operators, DOF variables etc.
