<div><font color="#1F497D">I have got it to work, but I still don’t understand why. It seems that the fields in MathEvalAniso have to be 1/(mesh_width)^2. But why?</font></div>

<div style="padding-left:35.4pt;">Hi,</div>
<div style="padding-left:35.4pt;"> </div>
<div style="padding-left:35.4pt;">I want to mesh a geometry with layers stacked in z direction, where each layer should have a mesh width in the xy plane, and a different one in z direction. I have tried to combine the Box, Min and MathEval Aniso fields to
achieve this (see attachment). But the mesh widths are not as I expect, in particular in layer 2 in z direction it should be 1/20 its height. What do I do wrong?</div>
<div style="padding-left:35.4pt;">How is the mesh width derived from the m11, m22 and m33 fields in MathEvalAniso?</div>
<div style="padding-left:35.4pt;"> </div>
<div style="padding-left:35.4pt;">Thanks for some explanations and hints,</div>
