<H2>There are many <A HREF="../../../src/snes/tutorials/index.html">SNES Examples</A> using PetscFE, such ex12, ex17, and ex62.</H2>
The PetscFE class encapsulates a finite element discretization. Each PetscFE object contains a PetscSpace, PetscDualSpace, and DMPlex in the classic Ciarlet triple representation.
