I am trying to make sense of the statement that the integration of the kernel over the volume should equal 1.
I am using the Wendland kernel in 2D and the function and constant is taken from DualSPHysics wiki. So I have two questions right now:
1. My Normalization approach is correct?
2. Do I ever use this rule in computation? I need to have W(q) with units for this to make sense
I hope somebody could help me out?
