Strip Casting Modeling

Can Atli

Hello,

I need to do a solidification modeling for the twin roll casting process. The solidifying metal upon contact with the rolls has a curved trajectory as opposed to a straight path in conventional continuous casting. I am not sure how i can define the transport term in this case. Another problem is, for the molten metal and the roll contact, is it ok to define only a rotating wall with a heat flux?

Thank you for your assistance
