This dialog is used to specify whether to use the Conduction solver or whether to run a Flow analysis on every iteration. The Conduction solver will be faster, but the Flow solver may provide a more accurate simulation.
To access this dialog, ensure that you have run the 3D mesher on your part, you have selected an analysis sequence that includes Cool (FEM), and in the Process Settings you have selected one of the Transient analysis options from the Mold temperature options drop-down menu. Then click on the Cool (FEM) Solver Parameters button. The variables in the dialog will change depending upon the Mold temperature options you select in the Process Settings Wizard.
| Dialog Property | Comment | Default value |
|---|---|---|
| Transient, part heat flux calculation | Select the solver you would like to use to calculate the heat flux. The conduction solver is faster, but the flow solver provides more accurate results. | Conduction |
| Number of part heat flux time steps | This applies to the temperature in the part. Specify how often you would like the conduction solver to determine the temperature of the part, during the Injection + packing +cooling time period you specified in the Process Settings Wizard. | For Conduction solver only |
| Transient mold temperature convergence tolerance | Enter a value between the limits specified. The convergence tolerance applies to the change in mold temperature, from one iteration to the next. The lower the tolerance the more accurate the result, but the longer the analysis. | 0.1000 |
| Maximum number of transient mold temperature cycles | Select the maximum number of mold-temperature iterations you would like the analysis to perform. If the result does not converge before this maximum value, you will receive an error message. | 100 |
| GPU options | Specify whether you want the software to detect and use a supported GPU (Graphics Processing Unit) card when running an analysis, to speed up the analysis. | Automatic |
| Number of threads for parallelization | Select one of the drop-down options to configure parallel computation. This will improve solution speed, especially for large models. | Automatic |
