 triangle 2D mesh. This checkbox is not present in Netgen 3D parameters
 because currently building a tetrahedral mesh with quadrangle faces is
 not possible.
+- <b>Set size by Surface Curvature</b> - if this box is checked in, then  
+prevents creation of meshes of desired coarseness else mesher defines 
+density of 1D and 2D mesh depending on curvature of faces and edges. 
+- <b>Fuse consignment Edges and Vertices</b> - prevents to merging of 
+nodes of edges which are coincident geometrically but are different topologically.
 - <b>Optimize</b> - if this box is checked in, the algorithm will try to
 create regular (possessing even sides) elements.
