3 days 16 hours LEHNING_1 albedo could run into a floating point exception in very wet conditions, due to Alb1 < -1.
Commit 1756, by Nander Wever
3 days 19 hours Typo.

4 days 14 hours Improving consistency in dealing with rounding errors in phase change.

8 days 13 hours Adding the missing case of mk 9 for a water layer. Note that otherwise, a<0, such that the cast to unsigned short int experiences an underflow and type >> 1000.
Commit 1753, by Nander Wever
8 days 13 hours Improving documentation.
Commit 1752, by Nander Wever
Apr 9, 2019
11 days 12 hours Setting initial snow salinity to 0 and disable the zero flux upper boundary condition for advection. Both modifications are for numerical stability, but it is not the desired setting for the model.
Commit 1751, by Nander Wever
11 days 12 hours Adding comments to understand the function call.
Commit 1750, by Nander Wever
11 days 12 hours Introducing stricter limits on the van Genuchten parameters for sea ice, for the sake of numerical stability. Additionally removing some obsolete code.
Commit 1749, by Nander Wever
11 days 12 hours Sea ice: introducing special condition to favour only evaporation, not necessarily condensation when solving richards equation, to prevent instabilities.
Commit 1748, by Nander Wever
11 days 12 hours For sea ice: when mass is removed from the domain, adjust the pressure head in saturated conditions, to reflect the new pressure distribution.

16 days 20 hours Correct saturated pressure heads in case of element splitting.
Commit 1746, by Nander Wever
Apr 1, 2019
19 days 10 hours Improvements with global (i.e., class-wide) switches for the boundary conditions, and attempts to improve the explicit scheme, but the results of that remain somewhat unsatisfying.
Commit 1745, by Nander Wever
19 days 10 hours Measured snow height could get below ground level when it was in fact not available. But it's not clear why measured snow height needs to be corrected, as in the next time step, the new measured hs value will be assigned. So only routines following …

21 days 19 hours Better search strategies
Commit 1743, by Mathias Bavay
21 days 19 hours Better search priorities

29 days 17 hours Decreasing convergence thresholds for Richards solver, to improve the stability of sea ice simulations.
Commit 1741, by Nander Wever
30 days 7 hours Bug fix for SafeMode (SafeMode 1 and 2 could never work because mass1 was set to 0 and never recalculated). Also slight improvement.

1 month 1 day Helping the stability of the Richards solver by forcing less exotic values for alpha and n.
Commit 1739, by Nander Wever
1 month 1 day Small, but important improvements for sea ice simulations with dynamic salinity transport. Particularly the iterative update of the weight of the sea ice, to provide a more accurate lower boundary condition, seems to be important.
Commit 1738, by Nander Wever
1 month 1 day Adding pressure head as a required field for the *sno file for sea ice simulations.
