Presently, the PETSc interface throws an error when one attempts to integrate a DAE discretized with Lagrange-Legendre discretization:
produces a log with a degrees-of-freedom error:
I suspect the code @eslickj wrote to collect differential equations and discretization equations is failing because this discretization method has continuity equations in addition to normal discretization equations. How exactly we want to handle this case is up for discussion.
