open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear sir/ madam

I am a beginner in telemac.
I'm using telemac2d to simulate that a wave transfer in the wave channel.

I have two questions:
1.it carry out well in Saint Venant EF,but the wavelength seem too long
2.I try to use Boussinesq eq in telemac2d,but it gives an error information 'EXCEEDING MAXIMUM ITERATIONS'.I used to modify the options:'MAXIMUM NUMBER OF ITERATIONS FOR SOLVER','TIME STEP','SOLVER ACCURACY' and when the 'MAXIMUM NUMBER OF ITERATIONS FOR SOLVER'=3000 it can carry out,but it's results are very bad.

what should I do to solve those problems?please help me!
I have attached my steering files.
Thank you for your help,

YU
