Wave Generation

Hi everybody,

I'm a new user of OpenFoam. I was trying to generate a wave using InterFoam but it's quit hard for a beginner! If somebody could give me some ideas that would be great

Hi,

there is a wave toolbox, have a look at
http://openfoamwiki.net/index.php/Contrib/waves2Foam

Dear Elvis,

Thank you for your fast answer and links. It's very helpful.. As I can see, I have to modify the solver absoluty to generate the wave? and not only set specific boundary conditions?

Hi,

waves2foam is a professional way "to do waves correctly", but you can do it differntly!
(i think you have to live with "reflecting boundary conditions" in that case if i am not mistaken)

See
http://openfoamwiki.net/index.php/Co...yBC#User-Cases

4.2 User-Cases
4.2.1 groovyWaveTank

An example of using groovyBC to generate 2nd-order Stokes waves. It is designed to run with interFoam

=>you have to adopt the groovy part to swak4foam to use with todays OF-versions

also take a look at that commercial OF-solver IHFOAM http://ihfoam.ihcantabria.com/
=>so waves can not be that trivial, if we find commerical support for that area

disclaimer:
I´m not using waves2foam of ihfoam etc. , I just know that ngj has build it,
and he gave his valueable contribution to the OF-community. And I read about ihfoam in the past

Hi,

not to forget that there is also navalFoam
http://www.cfd-online.com/Forums/ope...navalfoam.html

Hallo,

Allow me to add that last time I talked with Hrv Jasak, then navalFoam had been linked to a slightly modified version of waves2Foam.

@Elvis: Thank you for the kind words, and no, waves are not necessarily trivial, but it depends on the type of the problem.

Kind regards,

Niels

Hello everyboy!

Thank you very much Elvis! Now it works with waves2foam and it looks very clean..
