changes part accidentally slipped through. This problem is only on
trunk, on branches/dev/ it's fine.

|5 years 8 months ||Non convergence in soil freezing is now treated as a warning,
instead of an error, because we try to repeat the time step with a
smaller time step.

|5 years 8 months ||I never noticed that my simulations with Richards equation for snow
were actually never forming surface hoar... So now it does.
|5 years 8 months ||Because the "soil type" name "ALPINE3D" was
confusing (has basically nothing to do with alpine3d), I renamed it
to SNOFILE. Then, it takes the grain size specified in the sno-file
to define the soil types. This should be the default option. I also

ql only in case of explicit boundary conditions. In the implicit
case, the exchange coefficient determine the actual flux, so
limiting the fluxes in that case are basically only a po

changes in internal energy when soil with a freezing point
depression is in freezing state. The difference in heat capacity
between ice and water is a source or sink of internal energy.

be a discrepancy in the soil heat flux from the perspective of the
soil and the perspective of the snow. This approach averages both

collectsurfacefluxes()! The mess originates from the confusion about
the units of MS_RAIN.

balance of the soil. I made the mistake by not taking into account
water added and removed from the soil, which is basically a
source/sink for the heat capacity of the soil. The differe
