[waves2Foam] Modified the waveFlume tutorial and getting strange wave height

kenrichaiz · December 14, 2016, 02:27

Hello Niels, sorry to bother again. I have modified the waveFlume tutorial and input the wave parameters as attached. I've set the wave height to 0.04m. However, when i plot the surface elevation vs time of my probe (at the middle of the wave tank), i only get less than 0.02m wave height. the probe is also not within the relaxation zone area. Can i have your advice on this please?

The problem is your vertical resolution of 0.10 m, which is way bigger than the wave height.

Kind regards

Niels

yeap, you were right about my vertical mesh size. I've corrected and increased the vertical mesh resolution by 10x and change the wave height to 0.3m. However, the graphs obtained are not very reasonable. this does not happen when i set my period at 2s. I have no idea why. Please kindly advise me on this.
