1. Generalities

We want to store the resolution criteria, the residuals and the numbers of iterations of a calculation (requiring iterations) in a Data Structure RESULTAT.

These criteria are checked in routines NMCRCV and NTCRAR (and are printed on file MESSAGE).

To transfer these criteria from routines NMCRCV and NTCRAR to storage routines NMARCH and NTSTOC, we created Data Structures CRITNL for mechanical nonlinear calculation and CRITTH for thermal nonlinear calculation.
