Tutorial - irregularMultiDirection

For any directional wave generation (i.e. not perpendicular to the generation line), the number of paddles in the generation line must be greater than 1. However, in the irregularMultiDirection tutorial, nPaddle=1, which would not give proper results. I have attached an example (irregularMultiDirection_Tutorial_Extended_3D) of that tutorial with an extended domain (to have a better observation of the wave propagation) and nPaddle=50. Please note that nPaddle can be defined in constant/waveProperties. Please run this case with nPaddle=1 and nPaddle=50 for comparison.irregularMultiDirection_Tutorial_Extended_3D.zip
