Description of internal variables
==================================




The following table gives the correspondence between the number of internal variables accessible by *code_aster* and their description in the case of 2D modeling (D_ PLAN or AXIS):

Reminder: the first four internal variables (in the 2D case) under MFront are always the elastic deformations.

Reminder: the first six internal variables (in the 3D case) under MFront are always the elastic deformations.
