5 \n <b>Netgen 2D</b> and <b>Netgen 3D</b> hypotheses work only with <b>Netgen 1D-2D</b> and
6 <b>Netgen 1D-2D-3D</b> algorithms. These algorithms do not require
7 definition of lower-level hypotheses and algorithms (2D and 1D for
8 meshing 3D objects and 1D for meshing 2D objects). They prove to be
9 useful if lower-level meshing is homogeneous for all wires and faces

15 <li><b>Name</b> - allows to define the name for the algorithm (Netgen
16 2D (or 3D) Parameters by default).</li>
17 <li><b>Max Size</b> - maximum linear dimensions for mesh cells.</li>
18 <li><b>Second Order</b> - if this box is checked in, the algorithm will
19 create second order nodes on the mesh, which actually will become
20 \ref adding_quadratic_elements_page "Quadratic".</li>
21 <li><b>Fineness</b> - ranging from Very Coarse to Very Fine allows to set the
22 level of meshing detalization using the three parameters below. You
23 can select Custom to define them manually.</li>
24 <li><b>Growth rate</b> - allows to define how much the linear dimensions of
25 two adjacent cells can differ (i.e. 0.3 means 30%).</li>
26 <li><b>Nb. Segs per Edge</b> and <b>Nb Segs per Radius</b> - allows to define the
27 minimum number of mesh segments in which edges and radiuses will be
29 <li><b>Allow Quadrangles</b> - allows to use quadrangle elements in a
30 triangle 2D mesh. This checkbox is not present in Netgen 3D parameters
31 because currently building a tetrahedral mesh with quadrangle faces is
33 <li><b>Optimize</b> - if this box is checked in, the algorithm will try to
34 create regular (possessing even sides) elements.</li>
