Adding Quadratic Elements

MESH modules allows you to work with Quadratic + Elements.

+ +

Quadratic Edge in not a straight but a broken line and can be defined + by three points: first, middle and last. All more complex Quadratic + Elements differ from ordinary ones in that they consist of Quadratic + Edges.

+ +

To + add a quadratic element to your mesh:

+ +

1. Select your mesh in the Object Browser + or in the 3D viewer.

+ +

2. From the Modification + menu choose the Add item + and select one of the following:

+ +

To create any Quadratic + Element specify the nodes which will form your triangle by selecting + them in the 3D viewer with pressed Shift button. Their numbers will appear + in the dialog box as Corner Nodes + (alternatively you can just input numbers in this field without selection).The + edges formed by the corner nodes will appear in the table. To define the + middle nodes for each edge double-click on the respective field and input + the number of the node. All edges and the object formed by them will be + displayed in the Object browser. When all edges are defined you will be + able to click OK or Apply + button to add the element to the mesh.

+ +

Reverse + button for Quadratic Edges switches the first and the last nodes. For all other elements it reverses the element. +

2D Meshing Hypotheses

Max - Element Area hypothesis is applied for meshing of 2D faces composing - your geometrical object. Definition of this hypothesis consists of setting - the maximum area of meshing elements - (depending on the chosen meshing algorithm it can be triangles - or quadrangles), which will compose - the mesh of these 2D faces.
