Process Settings Wizard - Coolant Flow Settings tab

This dialog is used to select the friction formula to use in the Coolant Flow analysis, and whether to include minor losses and gravity in the calculation. You can also select whether or not to calculate the coolant temperatures.

To access this dialog, ensure you have selected Coolant Flow as the molding process, then click (Home tab > Molding Process Setup panel > Process Settings).

Dialog elements	Explanation
Minor Loss	There are 4 options; 3 options to use minor losses, and one to ignore them. Minor losses result from changes in geometry or added components to a channel system. They occur at inlet and exit transitions, expansion and contraction points, bends and elbows, tees, valves and pipe connections and fittings. These all cause the interruption of smooth fluid flow, resulting in minor losses of energy due to flow separation and mixing Calculate minor losses If you don't have access to data specific to the geometry changes, or added components used in your cooling system, the software can calculate generic minor losses based on the geometry information you provide. Use specified minor losses If you have the data, choose this option and enter the loss coefficient K factor information on the appropriate model element. This option provides the most accurate simulation. Calculate minor losses unless specified Use this option when you have a particular component that you know contributes significant minor loss that you want to capture, but you are content to let the software calculate the rest of the system for you. Ignore minor losses If you have no interest in the contribution of the circuit geometry and added components to the system pressure loss, select this option.
Friction formula	All of these options are used to solve for the Darcy Weisbach friction factor, f. Unless you have a particular preference for a particular approximation, use the default setting. Options include: SwarmeeJain - This is the default option, and the preferred approximation to the Colebrook-White equation. ColeBrook White - This equation is implicit in nature and needs to be solved iteratively. Haaland Serghides Altshul Evangelides
Calculate coolant temperatures	Select this option to include the Circuit coolant temperature result in the simulation
Simulate gravity effect	Select this option to include gravity in the simulation. This considers the height of the inlet and the outlet nodes, and calculates how gravity contributes to the coolant flow rate.
Edit gravity direction	This button is activated when you select Simulate gravity effect. Click this button to open the Gravity Direction dialog.
