What you need to provide hedge is a set of nodal values at the
interpolation nodes it generates for you. If you can somehow interpolate
your existing solution to those nodes, you should be good to go. For
example, on a triangle, first order nodes will sit at the vertices, and
second-order nodes will sit at vertices and edge centers. If you can
make those locations for your grid coincide with data you already have,
you don't even need to interpolate.

HTH,
