giving a time series as input for a free surface problem

Rising Star · October 28, 2015, 21:20

I'm facing this situation: I'm trying to simulate a wave flume (so it's a multiphase problem) with a given time series eta=(z,t) that I have to use as input. Do you have any suggestion on how can i set-up the inlet patch? how can I translate the eta information to the alpha.water?

Thank you for any help

Cheers

Filippo

IHFOAM (a modified inter foam version) can handle the wave flume. It handles regular (you specify H, T, etc) or irregular....via a time-series.

thank you very much for your answers

I'm already using the IHFOAM tool, but I can't use the free surface as input: as you said, I can use wave period, wave lengths, but I have the value of eta for a given timeseries, that I have to convert somehow as alpha.water field
