I am working on a solidification project, I want 2 stir the molten metal for 5mins then stop the rotating region from rotating, then open d gate (i.e after 5mins of stir) so that the molten metal can flow out. I want 2 also control d mass flow rate of the solid metal at inlet such that I will introduce it within first 2 mins of impeller rotation i.e first 2 mins of stir.

Pls, I need help in writing d script for
1) d impeller or stirrer motion
2)d gate ctrl
3)mass flow ctrl
The total mass of metal is 10kg
