Adding a Solution Setup to an Icepak Design

To add a new solution setup to a design:

1. Select a design in the project tree.
2. Click Icepak>Analysis Setup>Add Solution Setup.
   • Alternatively, right-click Analysis in the project tree, and then click Add Solution Setup on the shortcut menu.
   • If you have an existing setup, you can Copy and Paste it, and then edit parameters.

3. The Icepak Solve Setup Dialog dialog box appears.

4. On the General tab, enter a Name for the solution setup.
   Note:

   It is recommended that the following names not be used for a Solve Setup:

   • Feedback
   • Initial
   • Current
   • Field
   Note:

   The Enabled check box disables/enables a setup. Only enabled setups are run when you select Analyze All.

5. Enter the Maximum Number of Iterations for which the solution should run.
   Note:

   The lower right corner also contains a button for HPC and Analysis options. Here you can select or create an analysis configuration.

6. Under Problem Types, enable or disable Temperature or Flow to include or exclude thermal or fluid calcuations in the analysis.
   Note:

   Problem Types is active only when Temperature and Flow is selected in the Solution Type dialog box.

7. Under Flow Regime, select Laminar or Turbulent. If the flow regime is turbulent, click Options to open the Turbulent Flow Model dialog and select a model.
   Note:

   For detailed information regarding turbulence theory, see the Icepak Technical Notes Turbulence section.

8. If solving for radiation, select Discrete Ordinates or Ray Tracing under Radiation Model.
   Note:

   In addition to enabling radiation in a solution setup, it might be necessary to define radiation settings for boundary conditions that require it (for example, network face nodes). See Assigning Thermal Boundary Conditions for more information.

9. If solving a natural convection model, select Include Gravity.
10. Click the Convergence tab and enter values for the available parameters based on the selected turbulence model.
11. Click the Solver Settings tab.
12. If needed, under Initial Conditions, enter initial values for the available parameters based on the selected turbulence model.
13. Click Advanced Options to open the Advanced Solver Settings dialog.
14. If needed, enter Under-relaxation values.
15. Select Discretization schemes.
16. Under Linear Solver Options, select or enter the following settings for the available parameters based on the turbulence and radiation models (if applicable).
    • Type
    • Termination Criterion
    • Residual Reduction Tolerance
    • Stabilization
17. Click OK close the Advanced Solver Settings dialog.
18. If solving for solar radiation, click the Solar Radiation tab and select a Solar Load Model and define the North Direction Vector.
    • For Solar Calculator, define the Local Time and Position and Illumination Parameters.
    • For Specify flux and direction vector, define the Solar Flux and Direction Vector parameters.
19. If solving for radiation, click the Radiation tab and enter Flow Iterations per Radiation Iteration under Iteration Parameters. If you selected the Ray Tracing model, enter the Maximum Radiation Iterations.
    • For Discrete Ordinates, enter Angular Discretization values.
    • For Ray Tracing, enter the Faces per Surface Cluster under Cluster Parameters and the Resolution under View Factor Parameters.
20. Click OK to accept the solution settings and close the Icepak Solve Setup Dialog.
