The Cool analysis log contains the change in coolant temperature from coolant-in to coolant-out.
The analysis log contains a record of the analysis and can be accessed by selecting the Logs check box at any time during or after the analysis.
- External iteration
- The analysis first assumes an initial temperature distribution for the circuit metal temperatures, and performs a circuit Cool analysis based on these temperatures. It then performs a boundary element Cool analysis on the part and mold using the data obtained from this circuit network distribution. From this boundary element Cool analysis, new temperature distributions are obtained for the circuit metal temperatures. Based on these circuit metal temperatures, another circuit network analysis is performed and new boundary conditions are obtained for the boundary element analysis. Another iteration of the boundary element analysis is then performed and these iterations are continued until convergence is reached.
- Cycle time(s)
- This is the sum of the filling, packing, cooling, and mold-open time. When an automatic Cool analysis is performed, the cycle time is the result of the analysis along with the relevant temperature distributions.
- Avg temp iteration
- The boundary element method solves the average temperature distribution in the part. This average temperature is dependant upon the heat fluxes coming from the part into the mold, on the heat being extracted into the circuits, and heat loss from the outer boundaries. The heat flux solution and the average temperature solution are coupled and various iterations between the two solutions occur. The number of iterations between the flux and temperature distributions before internal convergence are recorded here.
- Avg temp deviation
- A solution tolerance is set in the advanced settings of the Cool analysis Process Settings Wizard, with a default of 0.1° degrees. The iterations will continue until the temperature solution is accurate to within this tolerance. You can monitor the rate of convergence of the average temperature equation by looking at this number. If the solution does not converge, then this number will never go below the specified value.
- Dif temp iteration
- The temperature difference equation is only applicable to Midplane part models or Dual Domain/3D models with inserts and parting planes. Midplane part models solve the average temperature of the part and the temperature difference across the part. Form this information, the top and bottom temperatures are obtained. The same is applicable to inserts and parting planes. The temperature difference equation is coupled to the average temperature, heat flux and coolant temperature difference solutions within an iteration. This value just gives you the rate of convergence of this equation, and if it is not converging, this parameter will indicate it. Convergence will occur when this value is smaller than the specified value.
- Dif temp deviation
- Provides an indication of the number iterations required by the temperature difference solver for internal convergence.
- Circ temp residual
- The coolant network solution is solved in conjunction with the boundary element method. This parameter tells you how much the coolant temperature distribution changes with every external iteration. As this parameter tends to zero, it shows that the coolant temperature distribution does not change much with successive boundary element iterations and a solution is near. The coolant tolerance is much tighter than the one for the part and at the end of the analysis the final error is printed out.
