Hello,

I am getting this error (below) in my Sisyphe simulations. Any ideas as to why?

LAYER AFTER BEDLOAD

The key information for the model crashing is this:
ERROR ON FRACTIONS LAYER 1 CLASS 1 POINT 6211 AVAIL-1= 1.498852668646578E-007
The total amount of the fractions in the active layer is larger than 1 in node 6211
This is probably a rounding error in the computations, which are hard to solve. However, in your case I see that the evolution has more than 90m. Is that what you were expecting? If not, sorting that error might solve the numerical error in the fractions as well.
