Adding nodes and elements


In MESH you can add to your mesh different elements such as:

To add a node or an 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, the following associated submenu will appear:

    From this submenu select the type of element which you would like to add to your mesh.

    Note
    All dialogs for new node or element adding to the mesh (except for the dialog for 0D elements) provide the possibility to automatically add a node or element to the specified group or to create the anew using Add to group box, that allows choosing an existing group for the created node or element or giving the name to a new group. By default, the Add to group check box is switched off. If the user swiches this check box on, the combo box listing all currently existing groups of the corresponding type becomes available. By default, no group is selected. In this case, when the user presses Apply or Apply & Close button, the warning message box informs the user about the necessity to input new group name. The combo box lists both standalone groups and groups on geometry. If the user chooses a group on geometry, he is warned and proposed to convert this group to standalone. If the user rejects conversion operation, it is cancelled and a new node/element is not created!

Adding 0D elements

Adding polyhedrons

There are two different ways to add polyhedral volumes.
If you select Node as Elements Type you will specify the nodes which will form the faces of your polyhedron by selecting the nodes in the 3D viewer with pressed Shift button and clicking the Add button to add the face in the list of Faces by Nodes, which will form your polyhedron. Note, that it could be very useful to toggle Polyhedron Preview checkbox to see the results of your selection.
The second way is somewhat simpler, however, there are cases when it does not provide you with the necessary level of precision. If you select Face as Elements Type, you will be able to select the faces which will form your polyhedron in the 3D viewer with pressed Shift button. If you've managed to obtain the necessary result, click the Apply or Apply and Close button. Your polyhedron will be created:
