5. 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.
