open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

at the moment i have a big problem by creating a culvert.
I tried to use the Bridge-example from the Telemac2d examplefolders, but this example doesn't work.

Which Value i should use for z1 and z2?

In the attachments you cand find my experimental project.

Best regards Michael

Hello

The example of bridge is not the smartest in your case, rather you can see the case siphon.
There is a full description of all the parameters you need in the user manual (section 13.2 CULVERTS)

I hope that this helps

with my best regards

Thank you for your help.

But it doesn't work.
The water from right stays on the right side but dont flow trough the siphons.

Hello

Are you sure?
In the listing, is written the flowrate that goes through the culvert. Is it written that this flowrate is nil ?

with my kind regards

Riadh

In the onscreen listing i can't see the flowrate from the culvert.
But in BlueKenue the node from the culvert has the same flowrate like the other nodes nearby.

Also there is no change to see between a model with and a model without culverts.

Best regards

This means that the culvert is not not well implemented. Which version of Telemac are you using ?
Can you add the subroutine buse.f to your fortran file and add some prints to see if really the culvert is well taken into account ?

At the moment i use the trunk version.
How do i add the buse.f to my fortran file and how could i make this prints?

Regards

Michael

Why you are usung the trunk version ? This is an unstable version and it is continuously changing. Moreover, we can not give any assistance to user for this version. Instead use the official release (V7P1r1)

with my kind regards

I use the trunk-version because i couldn't not find a way to simulate a rainfall with an hyetograph in the normal version.

I tried and now i added successfully the buse.f to my fortran file.

Best regards
