-Convert to/from Quadratic Mesh
-****************************************
-
-This functionality allows transforming linear meshes (or sub-meshes) to quadratic and vice versa.
-
-.. Note::
- that conversion of a sub-mesh most probably will produce a non-conformal mesh. Elements on the boundary between quadratic and linear sub-meshes become (or remain) quadratic.
-
-See :ref:`adding_quadratic_elements_page` for more information about quadratic meshes.
-
-*To produce a conversion:*
-
-.. |img| image:: ../images/image154.png
-
-#. Select a mesh or a sub-mesh in the Object Browser or in the Viewer.
-#. From the Modification menu or from the contextual menu in the Object Browser choose **Convert to/from Quadratic Mesh** item, or click *"Convert to/from quadratic"* button |img| in the toolbar.
-
- The following dialog box will appear:
-
- .. image:: ../images/convert.png
- :align: center
-
-#. In this dialog box specify:
-
- * If it is necessary to convert a linear mesh to quadratic or a quadratic mesh to linear. **Convert to bi-quadratic** creates some types of quadratic elements with additional central nodes: TRIA7, QUAD9 and HEXA27 elements instead of TRIA6, QUAD8, and HEXA20 elements respectively.
- * If it is necessary to place **medium nodes** of the quadratic mesh **on the geometry** (meshed shape). This option is relevant for conversion to quadratic provided that the mesh is based on a geometry (not imported from file).
