5. C modeling#

5.1. Characteristics of modeling#

We use the models AXIS then AXIS_DIAG.

Only half of the bar is shown (symmetry).

5.2. Characteristics of the mesh#

The mesh consists of 80 triangles of the same size. The following types are considered in succession:

Modelizations

Meshes

AXIS

TRIA3 TRIA6

AXIS_DIAG

TRIA3

5.3. Tested sizes and results#

We test the temperature at \(t\mathrm{=}1\) at a node in the plane of symmetry \((x\mathrm{=}0)\)

The solution complies with the analytical value at less than 0.1% for modeling AXIS and 0.13% for modeling AXIS_DIAG, with a time discretization of 100 time steps.
