Hi Luciano and Yvan, (First of all, thanks for sharing the presentation of Elisabeth Longatte, which I didn't find....) It seems we are working on the exact same problem ! My case look like this: fsi_case.png (pseudo 3D also) I also observed this strange displacement at the mesh interface. I also ha...

Hello Yvan, Thanks for your clear answer ! I was using an isotropic description for the mesh viscosity and indeed, the ALE values were not read when I did a restart. Using the GUI is enough as my case has no complex geometry, so I just changed the mesh viscosity description to orthotropic. Doing a r...

Hi Luciano and Yvan, I'm trying to use the restart option (with aster coupling) and it causes some trouble with the ALE module. To be clear, the restart works but does not take into account the mesh viscosity set in the previous simulation by setting it equals to 1 in the whole domain. Did you face ...

Hi (again) Yvan, So I have finally found what was my problem. I made some cleaning in the /tmp directory some days ago by deleting the *_FSI_ASTER_*.log, *_FSI_SATURNE_*.log and *_FSI_MILIEU_*.log . But I did not delete this salome files: - .omniORB_PortManager.cfg - .omniORB_PortManager.lock - .omn...

Hi Yvan,

So I imported the fsi_yacs_scheme.xml with succes in the salome's GUI.

I also checked with the this files: https://github.com/code-saturne/code_sa ... scheme.xml
I think there is no difference with mine.

Do you have any idea ?

Regards,

Paul

Hi Yvan,

It is very strange because it was working...

Thanks for your help. Here my "config.log" files.

Hi Yvan, So the guy in charge of the cluster has made some update in the software. And.... I have this error: th. 140190191470400 - Trace /home/A21173/smeca/yamm_build/V2017_0_2_build/V2017_public/modules/src/KERNEL/src/NamingService/SALOME_NamingService.cxx [1446] : CORBA::SystemException: unable t...

Hello Yvan and Luciano,

I was struggling with my case until this morning. I made the change as recommended by Luciano (thanks by the way), and it seems to work now ! I need to make some experimental comparisons and I'll keep you informed.

Hi Luciano, I didn't do too much with that case as I'm trying to set my own now. Yet, I've also changed it a bit, but only on the structural parameters like the initial velocity, young modulus, etc... Your problem seems to be related to the ALE method isn't it ? Negative volumes appear when the mesh...

Hi Yvan, So I made the coupling between Saturne and Aster work. It took me some times but I'll now run some more tests. Just to inform you what was my last problem, which was unexpected: the coupling procedure was not working when the "number of iterations for the fluid initialization" (NA...
