2. Modeling A#
2.1. Characteristics of modeling#
3D_ THH2MS modeling on 1 HEXA20 mesh.
1 second is simulated by 10 steps of time.
2.2. Result of modeling A#
The Figure 2.2-1 shows the evolution of the displacement dY as a function of time (the evolution is the same in the 3 directions, the test being perfectly symmetric). The post-processing is here done at node \(\mathrm{N8}\) at coordinates \((\mathrm{0,5 };\mathrm{0,5 };\mathrm{0,5})\). We make sure that travel evolves in a positive way.
A strong acceleration of the swelling is constant starting from 0.7 s, which corresponds to the moment when the swelling pressure stabilizes at 7 MPa (see above).

2.3. Tested sizes and results#
This test case has no reference value, so we make it a case of non-regression.
A test is carried out on the 3 directions:
