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:
