3. C modeling

3.1. Geometry

It is identical to modeling A.

3.2. Boundary conditions and loading

For the mechanical problem:

Boundary conditions and loads are the same as those in modeling A.

For the thermal problem:

The temperature is set at the origin: TEMP = 200.

A convective exchange with the outside is applied on the right edge.

Segment BORD_DRO: COEFF_H = 500. TEMP_EXT = 310.

A volume source is applied:

MOITIE1: SOUR = 18,000

MOITIE2: SOUR = 22,000

The other edges have zero flow.

3.3. Initial conditions

The thermo-mechanical calculation is transitory, with mesh adaptation every 2 time steps. The very first thermal calculation is initialized by a stationary calculation. The following thermal calculations are initialized by the temperature field obtained in the previous calculation and updated on the new mesh.

3.4. Benchmark results

	After adaptation 1	After adaptation 2	After adaptation 3	After adaptation 4
TEMP	3.02571345 102	3,03305718 102	3,0303801408 102	3,0887294988051 102
XX	1.24150129 10—2	1.23762443 10—2
DY	— 2.54077755 10—2	— 2.56470180 10—2

3.5. notes

In this series of adaptations, the degree 1 and degree 2 meshes necessary for thermal and mechanical calculation are produced at the same time.

The adaptation is controlled by error indicators, geometric areas or by the jump in movement.
