Hi Bärbel, no, the exact solution is just given on vertices of a (very fine) triangulation of the domain. But you are right, in my special situation I should always be able to rearrange the data on a regular, structured grid and then I can do the interpolation easily by hand and implement a Function<dim> object myself.
Thanks a lot, Jochen Am Dienstag, den 22.02.2011, 14:09 +0100 schrieb Bärbel Janssen: > Hi Jochen, > > does it mean you have the exact solution in any point of your domain?
