Hi,
I am attempting to model the continuous casting process of steel. The molten steel is poured in from the top of the geometry, it then enters the water cooled copper mould, and then it is subsequently water quenched. I am trying to model the heat flow (including solidification) and in the future, any thermal stresses incurring in the copper mould.
I am starting with a 2D planar geometry, using stationary turbulent conjugate heat transfer physics.
I keep getting the following error, and I cannot pin point the source of where the "negative power of zero" error is coming from.
I am a fairly new user, any advice on how to improve model will be greatly appreciated. Thank you.
