Question about the validity of output waves

I have a question about the validity of the output wave.

I have created a similar model based on the attached PDF paper.

The wave height is estimated to be about 0.08m from experiments, so I set dp = 0.008m.

The period and piston displacement were given as wave-making conditions, and the water level was measured.


      <objreal ref="10">

        <begin mov="1" start="0" finish="100" />

        <mvrectsinu id="1" duration="200" >

          <freq x="0.51" y="0" z="0" />

          <ampl x="0.0505" y="0" z="0" />




Since the wave height is determined by the above conditions, the result is shown in the graph.

The results are in green, with purple indicating the expected value. We can see that the simulation results are lower than expected, even taking into account the particle radius.

Any suggestions would be appreciated.


  • You have to be sure that you are using the correct amplitude, in any case you can use the automatic wave generation directly.
