open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everybody
I want to use Fudda to simulate a lake connected to four rivers. The basic data and parameters are all set. But this happened when running. Please help me. The attachment is the picture of the problem and the run file.

Hi
It looks like you have a problem with your geometry

Thanks for your help
I would like to ask you if "Reach" can be directly connected to the "Storage area". The Network I created and the river geometry are in the attachment below. If you have time, please check it out for me.

Storage area should be connected to reach with specific links.
You can't place them at an end of a reach

Regards

Okay, I understand. When I run another model, the results have an error:Error with the linear solver Y12M. Just like the picture below.Can you give me some suggestions?
Thank you!

This means your linear system couldn't be solved...
Try first without the storage area and add them step by step to see where the problem comes from

Hope this helps

After a quick look, there is some problems in you initial condition.
Upstream values in laws are not consistent with initial condition.
Values on the 3 reaches are not equivalent at the junction node
So impossible to solve the system at the first time step...

Thanks for your advice. It inspires me a lot. I'll keep trying.


Regards

Forgive me for being so troublesome for you. I have another question to ask you. The model run successfully, but there is no Graphs in the results. The picture below is Warnings.
