GitLab

The TS-GitLab will have to shut down towards the end of the year — please think about migrating your projects to GitLab.com or GitHub.
(This is still a very early message, meant to keep you informed. There will be more urgent ones in the future.)

add options for altering DG formulation in local operator

There are multiple options for different symmetry/penalty and upwinding combinations.

Upwinding:

  • fully weighted (none) (use K for weighting)
  • semi-upwinding (semiUpwind) (use K_0 for weighting and upwinding conductivity factor K_f^u)
  • full updwinding (fullUpwind) (only upwinding flux \mathbf{j}^u upwinding conductivity K^u)

Symmetry & Penalty

  • SIP (SIPG) = Volume + Consistency + Symmetry + Penalty
  • NIP (NIPG) = Volume + Consistency - Symmetry + Penalty
  • OOB (OOB) (Oden, Babuska, Baumann) = Volume + Consistency - Symmetry
  • IIP (IIB) (Incomplete Interior Penalty) = Volume + Consistency + Penalty

Harmonic weights:

  • Weights on (weights = true): Use harmonic weighting of (saturated) conductivities at intersections
  • Weight off (weights = false): No weighting
