DeltaK¶

Sets the sampling spacing in $\pvec{k}$ -space for the continuous part of the spectrum of the Fourier transform. The default values is

$\begin{eqnarray*} \Delta k = \frac{2\pi}{5d}, \end{eqnarray*}$

where $d$ is the diameter of the computational domain transverse direction.

Note

This parameter is ignored for fully periodic problems.
