Detailed Description

module for linear (first order) TVD reconstruction using slope limiters

Author

Tobias Illenseer

Jannes Klee

Currentely supported limiter functions:

• minmod
• mc (monotonized central)
• sweby
• superbee
• ospre
• pp (positivity preserving), NOT SUPPORTED in Fosite3D
• vanleer
• nolimit: for testing purposes only, disables limiting

Todo:

implement 1D/2D/3D PP limiter

fix broken output of slopes, uncomment the lines below yields segfault
