PETSc support for second-order elements?

[Matthew Knepley]

1) The library is not mature. It is alpha. However, it is being used for
    several projects.

2) The PCICE reader is just an example. Other formats could be easily
     implemented.

3) I am not sure I understand your question about quadratic elements. We
    do support higher order elements (see the Tutorial on the website). This
    has nothing to do with geometry, and thus you would just read in a tet mesh.

  Thanks,

     Matt
