u4.51.03 Operator STAT_NON_LINE

Summary:

Calculate the coupled mechanical or thermo-hydro-mechanical evolution, in a semi-static or in dynamic, with a non-linear structure.

Nonlinearity is related either to the behavior of the material (for example plastic) or to the geometry (for example in large displacements) or in contact and friction.

For details on the resolution method used, refer to the documentation. reference [R5.03.01]

Evolution can be studied in several successive studies (re-entering concept), either by continuation (the last moment calculated is the initial moment of the next calculation), or again starting from an earlier moment.

Produces an evol_noli data structure.
