Problem due to change of manning values
We have generated the run of a wave through a valley using constant manning values of 0.05 (in every cross section and at every elevation).
Then we changed the manning values from 0.05 to 0.07 and to 0.04 to see the effect on the wave.
There were no problems with manning values of 0.05 and 0.07, but it didnīt run with 0.04 ("error generated in output").
We tried to change the time step and interpolation distance, but this was not successfull.
Can you give us a hint?
Thank you very much,
Karin and Bethi
