This option enables the user to set the stages as fixed times during the cycle. Eventually, the solution should converge to identical cycles.
To access this dialog, select Time controlled from the Water cooling section of the Rapid Heating and Cooling inlet dialog, and click Specify.

Coolant control
|
The rate at which coolant is pumped through the channels can be specified in a variety of ways. Select the one which resembles your system most accurately:
- Specified pressure - Apply a fixed pressure to force flow in the circuit specified by the inlet node.
- Specified flowrate- Specify the total flow through all the circuits in the mold.
- Specified Reynolds number - A low Reynolds number (i.e. below 2300) produces laminar flow, which is characterized by smooth constant fluid motion. A high Reynolds number (i.e. above 4000), produces turbulent flow, which produces flow fluctuations that are good for heat transfer.
- Total flowrate (all circuits) - This option will show the user how the flow is distributed through each circuit if a total flow rate for the mold is specified. If different circuits in the mold have different geometries, these circuits will also have different flow resistances. The flow through the mold will always follow the path of least resistance. Hence the bulk of the flow will pass through the circuits that have a lower flow resistance, and less flow will pass through the circuits with a higher flow resistance.

Coolant inlet temperature
|
Enter the value for the temperature of the coolant that will be used to cool the mold, as it enters the circuits. The coolant inlet temperature will determine how quickly the mold cools down to the ejection temperature.
|
|
Duration
|
Enter the length of time you would like coolant in the channels to ensure that the part cools and can be ejected, before you purge with air in preparation for mold heating.
