/*! \page convert_to_from_quadratic_mesh_page Convert to/from Quadratic Mesh \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:
  1. Select a mesh or a sub-mesh in the Object Browser or in the Viewer.
  2. 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 in the toolbar.
