Convert to/from Quadratic Mesh


This functionality allows transforming standard meshes (or sub-meshes) to quadratic and vice versa. See Adding quadratic elements for more information about quadratic meshes. 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.

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 choose Convert to/from Quadratic Mesh item , or click "Convert to/from quadratic" button in the toolbar.

    The following dialog box will appear:

  3. In this dialog box specify:

    • if it is necessary to convert a standard mesh to quadratic or a quadratic mesh to standard. 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).
