Hi Bruno,
I only heard about applying flux limiters on advection/convection problems, but not on diffusion-related ones. This conforms with what I recently found in literature, but I may skipped something crucial. The equation of interest is the heat equation: <https://latex.codecogs.com/gif.download?%5Cpartial_t%20u%20-%20%5Cpartial_x%28%20k%20%5Cpartial_x%20u%20%29%20%3D%200> Do you think that flux limiters or TVDs work for a combination like this? <https://latex.codecogs.com/gif.download?%5Cpartial_t%20u%20+%20%5Cpartial_x%28%20f%28u%29%20%29%20%3D%200%20%5Cquad%5Ctext%7Bwith%7D%5Cquad%20f%28u%29%20%3D%20-%20k%20%5Cpartial_x%20u> I also suspect that I missed some lower bound on a stability constraint for the factor (k*timestepsize)? But from von Neumann analysis, I only get an upper one on that. I hope that one of you has any experience on that to share :) Best, Marc -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
