1. But

This macro-command makes it possible to test the laws of mechanical behavior from the point of view of robustness and reliability:

• in the mechanical case, the test uses a simulation of a multi-axial loading path on a hardware point, in order to verify the robustness of the numerical integration of the behaviors tested, of their insensitivity to a change of units, of the invariance of the result with respect to a global rotation applied to the problem, of the accuracy of the tangent matrix;

• in the case of control variables (temperature,…) this test verifies the correct consideration of the control variables on which the coefficients of the model depend, as well as the resulting deformation terms.
