) |
exponential upwinding stabilization algorithm
The arguments are values to compute the local peclet number
sprod | double – the scalar produkt between the velocity vector and the normal vector between two points |
distance | double – distance between two points |
D | double – diffusion/dispersion tensor part between two points |
