Hi all,

I have been using interFoam for a while and now i have a small question. I tried to find old posts, but don't know the relevant keywords to do searching.

Here it is:

Considering a simple dam break case, I need to release the water column after a period instead of from the beginning. How to implement?

Thanks in advance for any suggestion,

Jing

Specifically, can i set up a boundary condition that could be changed after a period (like remove a wall in DEM)?

The attachDetach mesh modifier will do what you want with the properly set trigger times.
