To conclude, we would like to say we have learned a lot on the instability.
We have been confronted with a lot of difficulties, like time calculation,
modelisation or precision of the caculation. These difficulties make us
obliged to better understand how a industrial computation code operates.
In fact, we needed to understand the physics and the code to reach our
The results seem to been good, but a more quantitative study would be necessary. We didn't have the time for that. What is encouraging is that we have find an instability which have the right wave number. So our results are at first sight good.
