Hi all,

I have some ocean data that I have taken the spectrum for. What I want to do is:

Calculate the amplitudes like this:

// Amplitude is the square root of the trapezoidal integral
        amp_[i - 1] =
            Foam::sqrt
            (
                (S[i-1] + S[i])
               *(nodeFrequency[i] - nodeFrequency[i - 1])
            );

(from JONSWAP.C) BUT instead of using the values from a traditional already implemented spectrum, I want to directly input my own calculated spectral values (S) from a text file.

This will be my first time altering any OpenFOAM code and I'm nervous about messing everything up and I don't know where to start on this task... does anyone have any advice on this? I imagine it will be something like:

Include the text file (in the place where the current JONSWAP or Pierson-Moscowitz calculation is), and calculate the amp, freq, etc from my S values in the text file.

First of all, is it possible to include a text file like that? If so, how might I do it?
