-\n This functionality allows you to transtorm standard meshes to
-quadratic and vice versa. See \ref adding_quadratic_elements_page "Adding quadratic elements"
-for more information about quadratic meshes.
+\n 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:
-- From the Modification menu choose the Convert to/from Quadratic
-Mesh item, or click "Convert to/from quadratic" button in the
+
- Select a mesh or a sub-mesh in the Object Browser or in the
+Viewer.
+- From the Modification menu choose Convert to/from Quadratic
+Mesh item , or click "Convert to/from quadratic" button in the
toolbar.

+- If it is necessary to convert a linear mesh to quadratic or a quadratic
+ mesh to linear. **Convert to bi-quadratic** option means same as
+ **Convert to quadratic** except that QUAD9 elements are created
+ instead of QUAD8, and HEXA27 elements are created instead of
+ HEXA20. Note that the choice is available only if the selected mesh
+ (or sub-mesh) contains both quadratic and linear elements, else the
+ direction of conversion is selected automatically.
+- If it is necessary to place medium nodes of the quadratic mesh on the
+geometry (meshed object). This option is relevant for conversion to
+quadratic provided that the mesh is based on a geometry (not imported from file).
