**v1.01.339** ZZZZ339 - Validation of the G calculation with initial constraints in 3D
==================================================================================

**Summary:**

This test is used to validate that the initial constraints are taken into account in the calculation of the energy restoration rate G in 3D. It includes 2 models: modeling A using classical elements (mesh crack) and modeling B using X- FEM elements (non-meshed crack).

This test has no physical meaning (the initial constraints are not self-balancing) and is purely computational.

For a physical example of taking into account an initial state, we can refer to test cases SSLP115 (2D) and SSLV116 (3D) to their associated documentation [:external:ref:`V3.02.115 <V3.02.115>`] and [:external:ref:`V3.04.116 <V3.04.116>`].

This documentation is deliberately brief.
