open TELEMAC-MASCARET The mathematically superior suite of solvers

Hey,

If the boundary condition of Telemac is set to 2 2 2, is it possible to have a fully reflection? In the sense that if I impose a one-dimensional propagated sin (or cos) shallow water wave at the boundary, when it arrives at the solid boundary and been reflected back, can we observe a standing wave?

I am asking because I did the simulation and found that the reflected signal is much weaker than the imposed signal. Is it a way to have fully reflection?

Merci!

Hello Quighui

glad to see that you're back with Telemac.
boundary condition 222 means only that the normal component is set to zero and that only the tangential component is kept. That's why you are observing a weak reflection. Actually your wave is loosing its normal velocity component and thus its kinetic energy.
I'm not sure that the way you are thinking about is feasable.

with my kind regards

Hey,

Thank you Monsieur! Yes I am now working with coupled Telemac and Tomawac =)! OK I will have a look how to make it possible cause I need to do long wave simulation towards the coast and its reflection.

Best regards,
