Piston movement for wave generation: convert free surface time series to piston movement in DualSPH

Hello

I have free surface time series data and I want to transform this data to the piston for wave generation,but I can't figure out how to implement it

I found that I can use the option of "linear motion from a file" for piston movement (using DesignSPH with freecad or directly in XML file) , from wavemaker theory I found the relation between the piston movement and wave generation,however, I don't know if it is validated in DUALSPHysics or there is a way to implement it .

another option is to use JONSWAP spectrum for irregular wave generation but I think it's better to use the real-time series that I have

thanks

  • How to create the piston motion to get the target surface time series is an issue related with wave theory... not related with our code itself...

    Sorry, you will need the asistance of some wave expert here to produce the time series of the piston position.
