The results give me the amplitude (referred to as H in the .pra file) and the phase (referred to as G). But how do you find the phase difference to be applied at different ends of the same open boundary?<br />e.g. the phase difference between open boundary 1a and 1b?<br /><br />And can someone explain what the V0 + u and F headings are in the .pra file?<br /><br />Any help would be much appreciated. Many thanks,<br /><br />GabrielGabriel Lim2019-11-28T18:23:50Z
