how to find wave amplitude
 
hi

i am sekhar. i am doing project using fluent software which is related to the generation of waves. i constructed a tank using gambit and using UDF i generated a wave.the program is similar to this #include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime) { vel[0]=(0.037098)*((1 - exp(2.303*time))*7.7528*cos(7.7528*time) + ((2.303*exp(-2.303*time))*sin(7.7528*time))); }

i want to know the amplitude of wave which i am generated.can u give me any ideas to finding this

thanking you,

sekhar

hi, I am windstar, i want to know the amplitude, wavelength of wave generated using this UDF too.

Hi

Would you please say me, how you write this udf? especially about velocity equation(vel) for wave. Could you please give me some references about finding that?

Cheers
