It is possible to apply a velocity time-dependent at a moving wall?

Hi Nicola,


this is certainly possible, I have programmed a BC in which you can specify the displacement of the boundary as a time series. Converting your velocity time series to displacement should be straightforward. I use it to drive piston and flaps to generate waves: https://www.youtube.com/watch?v=Pcg7CIowmhg



You can find all the information and examples in: https://olaflow.github.io/source-code/

Since the source code is available, you can modify the BC to suit your needs.


Best,


Pablo
