Excessive entrained air in an HPDC shot sleeve using constant speed slow shot profile | FLOW-3D CAST0:20
This video demonstrates Active Simulation Control being used to increase data output frequency when fast shot begins so that flow details can be captured. Flux surfaces are placed at the gates to measure the average velocity. When the average velocity exceeds 35 m/s, Active Simulation Control sets the output frequency to 0.0007 seconds for the duration of the simulation.
