d5.03.03 Introduce a new degree of freedom and associated boundary conditions

Summary:

What should you do when you add a new degree of freedom in one of the sizes DEPL_R, TEMP_R, or PRES_C?

In particular, what should we do so that we can « constrain » this degree of freedom through linear relationships that are dualized (AFFE_CHAR_MECA for example) or eliminated (AFFE_CHAR_CINE)?
