The coherence is by default set to 1:<br>
Geometry.AutoCoherence = 1; // Should all duplicate entities be
automatically removed?<br>
<br>
We usually use <br>
Coherence;<br>
when previously set to 0.<br>
<br>
This command has an influence on the geometry, not on the resulting
mesh. <br>
In your case, the geometry is ok, there are no duplicated nodes.<br>
However, it is not the case with the mesh. You should split the
surfaces that touch for voiding duplicated nodes, nodes of the mesh.<br>
