Hi Sara,
I stay on a failure with gaia and, I will be happy to understand my mistake.
I swept all the parameters of the manual (numerical, physical, temporal) with 250 calculations...
But, i did lot of tests on v8p2 and i also did some tests on v8p4: same diffilculty with abnormal formation of the breach.
With Sisyphe,some tests allowed me to have more consistent results quickly.
I join one version of *.cas files. Geometry and BC files with which I carried out the majority of the tests.
The objective of these calculations is to study the sediment transport through the breach: deposition, erosion and erosion pit.
Thanks
Best regards,
Gregory
