3. B modeling#

3.1. Characteristics of B modeling#

Modeling HHS in plane deformations. Coupling LIQU_VAPE_GAZ. 100 elements QUAD8.

In a second calculation, we test the automatic management of the time step.

Discretization in time:

  • \(\mathrm{1000s}\) in 20 steps of time

  • \(5000s\) in 20 steps of time

  • \(10000s\) in 10 steps of time

  • \(50000s\) in 20 steps of time

  • \(100000s\) in 20 steps of time

With the automatic management of the time step, we only give the 1st time step and the mandatory moments of passage (for TEST_RESU):

  • \(50s\)

  • \(5000s\)

  • \(100000s\)

The code manages the time steps by itself.

3.2. Results#

The results are practically the same as for modeling \(A\), which is logical considering that there is no thermal step.

Automatic time step management makes it possible to take 5 times fewer time steps.

3.3. Tested values#

2 non-regression tests are carried out for each calculation:
