<b>Netgen 2D</b> and <b>Netgen 3D</b> hypotheses work only with <b>Netgen 1D-2D</b> and

- <b>Name</b> - allows to define the name for the algorithm (Netgen
2D (or 3D) Parameters by default).
- <b>Optimize</b> - if this box is checked in, the algorithm will try to
create regular (possessing even sides) elements.

+- <b>Local sizes</b> - allows to define size of elements on and
+around specified geometrical edges and vertices. To define the local
+size it is necessary to select a geometrical edge or vertex in the
+object browser or in the viewer, and to click <b>On Edge</b> or <b>On
+Vertex</b> correspondingly. <b>Name</b> of the geometrical object and

+<b>Value</b> can be changed.
+- <b>Remove</b> - deletes a selected row from the table.
