Rotating wall BC
Hello foamers

My question was already asked before in this forum but I could not understand how to solve my problem: I need to impose to one or more patches a rotational velocity. How can I do this without modifying solvers? I saw about groovyBC, but I really could not understand how it works.
I'm using OF1.7 and simpleFoam with snappyHexMesh.

Thanks a lot!

I think this is the syntax for a rotating wall velocity.

type rotatingWallVelocity;
origin (0, 0, 0);
axis (0, 1, 0);
omega 100; //rev/s, I believe

hope it helps.

Perfect!! It works great!
Thanks a lot!

Unfortunately there are many many things that are undocumented like this one...
