Diffusion module

• Current State
• ToDos

This is the according repository to the diffusion module we discussed earlier. With this readme I will document all my steps I've done and will do.

Current State

• 1D diffusion is possible by setting bc at left/right end by hand by setBoundaryCondition() or use the default value (Neumann with gradient 0)
• Always set concentrations/diffusion coefficients by using std::vecto

• Set concentrations of ghost zones by defining them via a list tuples.

  • index 0 points to the left ghost zone
  • index 1 to the right ghost zone
• simple datastructure, which is currently just a class called BTCSDiffusion

ToDos

• keep sparse matrix in memory
• allow different boundary conditions at the ends and also inside the grid
• implement 2D diffusion
