- * 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).
