open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi
I'm trying too -for the first time- to simulate tom+t2d coupling, starting from littoral example files.

if I use in T2D the c.limits 455 at lateral side (like example) simulation stops with message "more prescribed elevations are required"
if I set lateral side as 222 (close wall) the simulation goes very slow, tomawac gives results, but not T2D.
I attached my files.
can someone help me?
thanks
F.L.
