Detailed Description

template<class scalar>
class NiHu::laplace_kernel< space_3d< scalar > >

Kernel of the 3d Laplace equation.

Template Parameters

scalar

The space scalar type

Definition at line 148 of file laplace_kernel.hpp.

Member Function Documentation

eval()

template<class scalar >

template<unsigned order>

void NiHu::laplace_kernel< space_3d< scalar > >::eval ( scalar  r, scalar *  f  ) const

inline

Evaluate the kernel and its derivatives.

Template Parameters

order

The derivative index

Parameters

[in]	r	The distance parameter
[out]	f	Allocated space for the results

• For order = 0 the kernel \( G(r) \) is computed.
• For order = 1 \( G'(r) \) is computed.
• For order = 2 f[0] = \( G'' - G'/r \), f[1] = \( G'(r)/r \).
