When you split a row of hexa elements, the preview function is available so you can see exactly which elements will change.  A row is defined by a hexa element and two nodes diagonally across a face of that element.  The split pattern is applied to that element and propagated through to the next element beyond it, continuing until a free face or a penta is encountered.  Elements in the same row that are located before the selected element are not altered.

When you split elements whose nodes are associated to a surface, the new nodes created are also on the surface.  To associate a node to a surface, use the Node Edit panel.

All split operators work on both first and second order elements.
