Add vtk Biquadratic element

[jginternational]

📝 Description
Add 9 noded quadrilaterals to VTK output

Implements #11703

[philbucher]

is the nodal ordering the same in kratos and vtk?

In Kratos:
https://github.com/KratosMultiphysics/Kratos/blob/master/kratos/geometries/quadrilateral_3d_9.h

 * The node ordering corresponds with:
 *      3-----6-----2
 *      |           |
 *      |           |
 *      7     8     5
 *      |           |
 *      |           |
 *      0-----4-----1

In VTK

The ordering of the eight points defining the cell are point ids (0-3,4-8) where ids 0-3 define the four corner vertices of the quad; ids 4-7 define the midedge nodes (0,1), (1,2), (2,3), (3,0) and 8 define the face center node.

is the nodal ordering the same in kratos and vtk?

@philbucher it seems to be the same

In GiD, just imagine that we start from 0, like real computer science engineers

nice!

Cuando tus alumnos intenten mallar con malla de cuadrilateros de 9 nodos, les dará un fallo.
Tan solo tienes que decirles que en el arbol de datos vayan a Results > VTK y deshabiliten la escritura de resultados para VTK
