Hye,

In the dam break case, I changed the location of water column and placed it at the top and, at the bottom air is placed as shown in the attachment.

The interface between the water and air is straight at time t=0 as described in the setFields dictionary by having the boxtocell '' box (0 0.292 -1) (0.584 0.584 1)''

But i wanted to change the shape of the interface at t=0 to something like a function of this form y=0.292 + 0.005cos(2x) where x is the horizontal distance from the centre of the whole geometry.

Any suggestions please.

Thanks
Vivek

funkySetFields or swak4Foam on the openFOAM wiki.

Best,

Hello vivek
I want to simulate dame break study with following assumption
1) The whole case is tilted to 5o degree how should I do with the mathematical formulation and using swak4foam utility

You can refer to the following webpage for understanding how to use swak4foam utility https://openfoamwiki.net/index.php/Contrib/groovyBC
