open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,
I'm actually working on wave-structure interactions and I'm calculating the overtopping on dikes/seawalls etc. I'd like to know if it's possible to use Telemac series for the simulation to compare its results with the results obtained with other methods.
-Are there any examples of the use of telemac series for that ?
If not :
-Should I couple tomawac with telemac2d (or is it better to use TELEMAC 3D) ?
-The calculation domain of Tomawac should normally end before reaching the structure, but what about the telemac 2d/3d one?
Thank you in advance
Regards
Mehdi
