How to set transient ang velocity?

edi ghirardi

Hi to everybody,

I'm studying liquid sloshing in a partially filled 3d tank submitted to transient linear accelerations and transient angular acceleration around one axis. I set the transient linear accelerations via a .scm file that reads an input file and changes the gravity components in the Operating Conditions panel depending on the time step. Up to now I'm able to set a constant angular velocity by the Bound. Conditions>Fluid>Moving Reference Frame option (I also set the walls as Moving Walls rotating at 0rad/s referring to the adjacent cell zone). How can I do to change it during time? Is it possible to use another .scm file or what?

Grazie (thanks),

Edi.
