streamfunction coefficients
 
hi
I am using Fentons Fourier program to produce streamfunction wave theory coefficients (Bj & Ej). but in results, wave propertis are in contradiction with Inputs! I do not understand the reason for this and I am confused.I would be very grateful if anyone could help me.

wave propertis: H=0.11, d=0.3, L=0.95, T=0.75

Fourier:
0.37 H/d
Wavelength Measure of length: "Wavelength" or "Period"
3.1617 Value of that length: L/d or T(g/d)^1/2 respectively
1 Current criterion (1 or 2)
0 Current magnitude, (dimensionless) ubar/(gd)^1/2
20 Number of Fourier components or Order of Stokes/cnoidal theory
1 Number of height steps to reach H/d
FINISH

Results:

# Solution by 20-term Fourier series

# Height/Depth: 0.370, 87% of the maximum of H/d = 0.423 for this length:
# Length/Depth: 3.16
# Dimensionless Period T*sqrt(g/d): 4.22
# Current criterion: Euler, Dimensionless value: 0.000

# Stokes-Ursell number 0.047

# Integral quantities - notation from Fenton (1988)
# (1) Quantity, (2) symbol, solution non-dimensionalised by (3) g & wavenumber, and (4) g & mean depth
# Water depth (d) 1.9873 1.0000
# Wave length (lambda) 6.2832 3.1617
# Wave height (H) 0.7353 0.3700
# Wave period (tau) 5.9494 4.2203
