No, you have to write a weak formulation. There is an early
implementation of a generalized collocation method in getdp, but not
ready for general use yet.

You will need some sort of upwinding if you plan to solve a
convection/diffusion equation (e.g. a SUPG method in a finite element
context). Tell me if you are interested in developing such a method.

We were planning to put a library of examples on the net, but the
project has been delayed due to various reasons (the main one being the
lack of time...). Try a search in the mailing list archives with the
keywords 'heat' or 'thermal formulation'. There is also some material
about the heat equation in the slides available on the web site.
