Hi,
I have tried to establish a model to simulate the flood in a complicated river network, when I establish and run the model in the fudaa enviroment for the first time, everything is ok,but when I save the case and reopen it, there is a red color word "extreme" appeared in the right information pannel, and the model can't run, and there is an Error window shows me "Probleme lors de la conversion en ficher cas ....",it seems like there is something wrong with the geometry of the river network, but I am very sure there is nothing wrong with the geometry.There must be a limit on the size of the problem, How big is it? what is the extreme? and what can I do to break the extreme?
Hope for your kindly help!

Hi, I am sorry to bother you again, I just found when the count of reaches in the model is greater or equal 100, when I reopen the model, it will show me the error again.
There are 3 attachments, and from the summary files, you can see when the model has 100 reaches and it is reopened, there really has something wrong with the geometry.
The count of reaches in a model can't beyond 100, is it right? If I have more than 100 reaches in the model, what can I do?

Regards!

I'm not sure and don't have time now to check in detail but it's possible that a limit exists for the number of reaches and if so it's possible this limit is 100...

About the solutions...

I see in your structure that there is some junctions with only 2 reaches. This means it's possible to merge the reaches and by consequence reduce the total number...

Otherwise, I advise you to try to move to the QGIS plugin dedicated to mascaret model management...
This will force you to create again your model as there is import function from an old model but I'm quiet sure there is no limitation on the number of reaches...

Kind regards

Christophe

exatto OFFLINE Fresh Boarder Posts: 23	Thanks a lot for your timely reply!But I have further question. I have installed mascaret plugin in QGIS 3.6.3 sucessfully, but when I tried to create a new model, the plugin can't work well. and the attachment is the video of my operation. Where can I find a manual for the plugin?

exatto OFFLINE Fresh Boarder Posts: 23	OK,I think I have found the answer myself! you can set the "max size of files read by fudaa-Mascaret" in the window that activated by the "output parameters" menu item !
