Detailed Description

template<typename TDerived, Size D>
class Kernel< TDerived, D >

Base class for all SPH kernels.

Provides an interface for computing kernel values and gradients. All derived class must implement method valueImpl and gradImpl. Both function take SQUARED value of dimensionless distance q as a parameter. Function value returns the kernel value, grad returns gradient DIVIDED BY q.
