Detailed Description

Second-order finite volume discretization stencil coefficients.

The stencils are defined using 9 coefficients corresponding to i+1, i and i-1 respectively in each of the three directions (see table below).

Coefficients for the first derivative

|   | +1  | 0   | -1  |
|---+-----+-----+-----|
| i | c00 | c01 | c02 |
| j | c10 | c11 | c12 |
| k | c20 | c21 | c22 |

Coefficients for the second derivative

|   | +1  | 0   | -1  |
|---+-----+-----+-----|
| i | s00 | s01 | s02 |
| j | s10 | s11 | s12 |
| k | s20 | s21 | s22 |

Coefficients for the filter

|   | +1  | 0   | -1  |
|---+-----+-----+-----|
| i | f00 | f01 | f02 |
| j | f10 | f11 | f12 |
| k | f20 | f21 | f22 |
