3. Modeling A#
In this modeling, we consider the structure in \(\mathrm{2D}\). The classical finite element method is used. Since the crack is meshed, the exchange condition between the lips of the crack is applied using the keywords GROUP_MA1/GROUP_MA2 of the keyword factor ECHANGE_PAROI of the operators AFFE_CHAR_THER and AFFE_CHAR_THER [U4.44.02]. This modeling is used as a reference for the future.
3.1. Characteristics of modeling#
We use the PLAN model of the THERMIQUE phenomenon.
3.2. Characteristics of the mesh#
The structure is modelled by a regular mesh composed of \(100\times 100\) QUAD8, respectively along the axes \(x\) and \(y\). The crack is meshed.
3.3. Tested sizes and results#
The temperature is tested at the end of the last time step (\(t\mathrm{=}1\text{.}s\)) at points \({P}^{\text{+}}\), \({P}^{\text{-}}\) and \(Q\) (see Figure).
