4 Split bi-quadratic into linear
5 ******************************
7 This functionality allows to split bi-quadratic elements into
8 linear ones without creation of additional nodes.
12 * bi-quadratic triangle will be split into 3 linear quadrangles;
13 * bi-quadratic quadrangle will be split into 4 linear quadrangles;
14 * tri-quadratic hexahedron will be split into 8 linear hexahedra;
15 * quadratic segments adjacent to the split bi-quadratic element will be split into 2 liner segments.
