17. O modeling#
17.1. Characteristics of modeling#
We use a 3D modeling in non-linear thermal with hyper-reduction of the model and finite element correction (option CORR_COMPLET).
17.2. Characteristics of the mesh#
The mesh contains 216 elements of type HEXA8.
17.3. Tested sizes and results#
17.3.1. With CORR_COMPLET#
The value of the temperatures obtained with a hyper-reduced model (with correction) is tested by compared to those obtained in the complete model:

17.4. notes#
We can see that the calculation with CORR_COMPLET is a bit better on the evaluation of temperatures.
