**v3.04.114** SSLV114 - 2D and 3D solid body movements
============================================================

**Summary:**

This test validates (in 2D and 3D) the LIAISON_SOLIDE keyword from the AFFE_CHAR_MECA command.

This keyword is used to rigidify a set of nodes by linear relationships expressing that the displacements of the "rigidified" nodes are linked together by the equation:

:math:`U(M)\mathrm{=}U(A)+\Omega (A)\mathrm{\wedge }\mathit{AM}`

This equation is only valid for small trips.

The problem tests 2D and 3D as well as special cases:


* nodes combined geometrically (2D and 3D),


* aligned knots (in 3D).
