To specify the circuit friction formula

The friction formula reduces the Moody diagram to a programmable form, so that the friction factor, f, can be determined. The friction factor determines the frictional losses in a channel network, and is dependent on the channel equivalent sand grain roughness factor and the Reynolds number of the fluid in the channel.

Note: The default formula is the Swarmee-Jain equation.

This task is valid for the following mesh types:

and assumes you have imported a model of a cooling circuit and meshed it.

  1. Click (Home tab > Molding Process Setup panel > Process Settings).
  2. In a Coolant Flow analysis
    • In the Process Settings Wizard - Coolant Flow Settings dialog, click the down arrow associated with Friction formula, and select the appropriate option from the drop-down menu.
    In a Cool analysis
    • In the Process Settings Wizard - Coolant (FEM) Settings dialog, click Cool Solver Parameters.
    • In the Cool Solver Parameters dialog, click the down arrow associated with Friction formula, and select the appropriate option from the drop-down menu.
    In a Cool (FEM) analysis
    • In the Process Settings Wizard - Coolant (FEM) Settings dialog, click Cool (FEM) Solver Parameters
    • In the Cool (FEM) Solver Parameters dialog, click the down arrow associated with Friction formula, and select the appropriate option from the drop-down menu.
  3. Click OK to close the dialog, and continue with other analysis setup tasks.
