v1.01.127 ZZZZ127 - Validating the LIAISON_MAIL keyword

Summary:

This test validates the LIAISON_MAIL keyword from the AFFE_CHAR_MECA and AFFE_CHAR_THER commands. This keyword generates linear relationships between the degrees of freedom of the nodes with 2 edges that are placed opposite each other. The programming is validated in 2D and 3D by inter-comparison with a similar calculation where the relationships between degrees of freedom are directly entered by the keyword LIAISON_DDL.

We also validate:

• the geometric transformation (rotation/translation) applied to one of the edges.

• the restriction of DDLpris in relationships between degrees of freedom.

• the LIAISON_CHAMNO keyword from the AFFE_CHAR_THER command (B modeling).
