Dambreak initial condition sine wave

joshmccraney · August 8, 2019, 16:23

Hi all!

I'm running the tutorial dambreak, and have change the geometry to a rectangle (no bump on the bottom) and the initial condition to a circular arc (see image)

Do you know how I can customize this further, like make the interface a sine wave?

Hello,
Take a look to this post: Sinusoidal initialisation of initial holdup field.

You can use the suggested utilty waves2Foam or some other tools like:

funkySetFields: http://openfoamwiki.net/index.php/Co...funkySetFields
swak4foam: https://openfoamwiki.net/index.php/Contrib/swak4Foam

For a recent version of swak4foam you can check this repository and you can find the installation instructions.
