ProgressionZUpper¶

Type:	float
Range:	[0, inf]
Default:	2.0
Appearance:	simple

The layer discretization in $z$ -direction, $[z_0, z_1, \dots, z_N]$ , is controlled by the maximum side length parameter MaximumSidelengthZ for the entire layer, that is,

$\begin{eqnarray*} z_{i+1}-z_{i} & \leq & \mathrm{MaximumSidelengthZ}, \end{eqnarray*}$

and the maximum side length at the upper interface (MaximumSidelengthZUpper), i.e.

$\begin{eqnarray*} z_{N}-z_{N-1} & \leq & \mathrm{MaximumSidelengthZUpper}. \end{eqnarray*}$

With this parameter it is controlled how aggressively the mesh is coarsened with larger distance to the upper interface. It is guaranteed that,

$\begin{eqnarray*} \frac{z_{i}-z_{i-1}}{z_{i+1}-z_{i}} & \leq & \mathrm{ProgressionZUpper} \end{eqnarray*}$
