Detailed Description

Laplace filter for LES.

Kernel                 as filter          as Test filter with ratio 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Box filter:            g = delta2/24  ->  g = delta2/6
Spherical box filter:  g = delta2/64  ->  g = delta2/16
Gaussian filter:       g = delta2/24  ->  g = delta2/6
