6. D modeling#

In this modeling, the extended finite element method (X- FEM) is used.

6.1. Characteristics of modeling#

We use the 3D modeling of the THERMIQUE phenomenon.

6.2. Characteristics of the mesh#

The structure is modelled by a \(\mathrm{3D}\) mesh composed of \(25984\) HEXA8. The crack is not meshed.

6.3. Tested sizes and results#

We test the temperature at the end of the last time step (\(t=1\text{.}s\)) at nodes \({P}^{\text{+}}(0)\) and \({P}^{\text{-}}(\pi \mathrm{/}4)\) (see Figure). To do this, the temperature field is tested after using operators POST_MAIL_XFEM and POST_CHAM_XFEM.
