Hello, I have a 2-d heat equation that I want to simulate with Finit Element Method, to do this, I'm looking for an example solving 2D poisson equation with FEM (DMDA or DMPlex). Is there an example like this ? Thanks a lot. Olivier Bonnefon -- Olivier Bonnefon INRA PACA-Avignon, Unité BioSP Tel: +33 (0)4 32 72 21 58
