Piston vs flap to generate waves
What is the difference and advantages/disadvantages of using a piston instead of flap to generate waves?
The piston-type wave generation is preferred usually for shallow water (depth =< 0.05 wavelength) conditions or intermediate water conditions when the trajectory described by the water particles is a very flattened ellipse which results in a almost uniform velocity distribution along the water depth. To move all water particles along a vertical column with a uniform velocity, a piston is the ideal choice.
For deep water conditions or conditions very close to deep water, the water particles move along a circular or elliptic orbit that reduces gradually from the free surface to the bottom. Therefore, a flap-type generation is a better choice.
I want model a flap type wave generation in liquid sediment case. but example model of flap type in Main doesn't work in this case.
could you please help me?
Multiphase code is not compatible with every option. Check the documentation.
Also please open a new subject when you have a question, rather than re-opening something old.
