Jérémie Roques International Volunteer; Hydrological mapping and model implementation

Hello;

Thanks Mathieu for this new answer, this make now complete sense when I look free space on my disk…
Well; I am using a rectangular grid and the courant number was the estimated one of the simulator. So enlarging grid size might be the only solution I have…
I will try this with a mesh grid as well.
Thanks a lot

Hi all;

By running my Mike 11 with flood mapping option and mike 21 models I respectively get following messages:
- “error. DfsWriteItem TimeStep return code is 2002”
- “WriteDataItem: Write error"

Does those messages mean that my computer miss memory?

Actually; I wanted to reduce Courant Number and tried to switch from a 1h to a 15m time step (CoN from 634 to 158; still too much… ).
Is there a better way to reduce CoN; enlarging channels?

Thanks

Hello;

Thanks Mathieu for this quick answer.

I finally managed to fix the issue by completely resetting my model including some parameters (dfs2 and dfs0).
I am now facing another issue and will open a new topic for that =/.

Thanks again. Best

Hi all;

I am facing an issue with my Mike 21 HD model. This is certainly related to the complexity of the field I am studying (deltaic floodplain) but, more probably, to my lake of knowledge on Mike software’s and mistake from my side...

Basically the computation start but don't give complete results even if the process bar shows 100% completion. With or without  boundary conditions, the model react the same way and there is no warning or error messages in the log file.

Short talks are more efficient than long speeches so please find attach logs for both with or without boundary conditions simulations.

Does anybody have an idea where my problem might be from?

Thanks

Jeremie
