EDF 30254 - quadratic to biquadratic : several problems
For biquadratic hexa was fixed next problems: * Volume and AspectRatio was equal 0 * Create boundary elements don't creating faces on this volume type * Fixed problem with free nodes after convert quadratic <-> bi-quadratic * Fixed problem when for volume with type BiQuadratic Pentahedron boundary elements for triangle side is quadratic and not bi-quadratic * Added missed fix for negative volume
