- for the distribution of the stochastic parameters of the Detailed check (LogNormal instead of Deterministic/Normal)
- for the state parameter which is equal to -0.06 instead of -0.03
- for the grain diameters:
- for Calais sand : D50 = 230 μm (instead of 180) and D15 = 130 μm (unchanged)
- for Compacted sand : D50 = 210 μm (instead of 160) and D15 = 110 μm (unchanged)
- for the Detailed check, the required probability of failure is 1 per 40000 years instead of 1 per 4000 years and the migration velocity is 0.5m/year instead of 10 mm /year.
For case I, the same input as case H is used except that the Detailed check is not performed.
Benchmarks results
For each cases, the Global and Detailed checks are worked out in an Excel spreadsheet.
...
Overall check: Global passes and Detailed checks fails, that's not logical, so a warning message is displayed in the Overall check.
