solitary wave

in DualSPHysics v4.4

hi guys

i want to simulation solitary wave in DualSPHysics v4.4 but i cant found the Theory of generation. i try to define a motion with linear motion from a file but is not correct. how found Theory of generation 1:Rayleigh (Serre 1953), 2: Boussinesq (Goring 1978) 3: KdV ?

    hi guys

    i want to simulation double solitary wave in DualSPHysics v4.4 .my waves have Same wave height when i do this my result not same.

    how can i do for the periods and height to be same?i want to check changes of the <startcoef2> in my case.
