Hello:
Thanks for your attention.
I want to do some exercise just like the tutorial of TELEMAC-2D, and I want to give a dry domain at the start of computation, so ,I set the keyowrd as INITIAL CONDITIONS = 'ZERO DEPTH'. And give the Q(flow) at upstream, Z(water level) at downstream, but there is always something wrong whih liquid boundaries file during computation. Is there some matters needing attention when I give the Q and Z in liquid boundaries file or other things needing to edit in steering file ?
Thanks for your help.
Regards

Hello

Teleamc is not able to handle liquid boundaries (with prescribed discharge) when these latters are completely dry.
You have first to wetten at least locally the boundary area and then run wil work well.

with my kind regards

Hello Riadh:
Thanks for your reply.
Is that meaning I have to use CONDIN subroutine to discribe some points of the boundary in order to wet locally. Is there any other method to do it, because I'm a new user of telemac and I don't konw how to use subroutine, or, is there any examples for this? I haven't get the method to usd CONDIN subroutine in the user manusl.
Thanks.

Hello

Yes you can use condin and wetten areas around boundaries. You can do the same job easily using blue kenue:
It is exactly the same procedure when you add in your geometry file a layer BOTTOM or BOTTOM FRICTION, you can add a layer called WATER DEPTH in which you can interolate initial values. Then, you have to use this gemotry file as a restart file (See the user manual to know how to use a previous computational file).

I hope this helps
with my best regards
