25.21 Checking Your Case Setup

After you have set up your case, and prior to solving it, you can check your case setup using the Case Check panel (Figure  25.21.1). This function provides you with guidance and best practices when choosing case parameters and models. Your case will be checked for compliance in the grid, models, boundary conditions, material properties, and solver categories. Established rules will be available for each category, with recommended changes to your current settings. At your discretion, you may elect to apply the recommendations, or keep your current settings.

To access the Case Check panel (Figure  25.21.1), go to

Solve $\rightarrow$ Case Check...

If there are no problems with your case setup, then an information dialog box (Figure  25.21.2) will appear stating that no recommendations need to be made at this time, otherwise, the Case Check panel will open.

Figure 25.21.1: The Case Check Panel

Figure 25.21.2: The Information Dialog Box

In the Case Check panel, each of the tabs Grid, Models, Boundary Conditions, Material Properties, and Solver may contain recommendations. For each of the tabs that are enabled, best practices will be listed.

In some cases, the panel will be split based on the method that the recommendation is applied. There are two ways you can apply the listed recommendations:

Automatic Implementation   : FLUENT applies the change for you.

Manual Implementation   : You will manually change your case settings.

Automatic Implementation

To the left of each of the recommendations listed under Automatic Implementation (e.g., Figure  25.21.4), there is an enabled Apply check box. An enabled check box will result in FLUENT applying the change to your case automatically. If there are some recommendations that you do not want FLUENT to implement automatically, then click the Apply check box to toggle off and disable the implementation of a particular recommendation. After going through all the tabs and determining which rules you want applied automatically, click the Apply button at the bottom of the panel. Changes to your settings will be applied to all recommendations throughout the panel with an enabled Apply check box. FLUENT will print a message in the console notifying you that the applied recommendation has been implemented.

FLUENT will ask you if you want to save the case before proceeding to the next step. If you choose Yes, the Select File dialog box will open allowing you to save your case with the new settings. If you select No, all the changes made to the case file will be lost once you exit FLUENT.

Manual Implementation

For recommendations that are listed under Manual Implementation, FLUENT cannot apply the changes for you. Therefore, if you opt to make a change to your current settings, based on the listed recommendations, then you will need to manually make the changes by opening the affected panels and applying what was recommended.

To the right of the recommendations is a ?, which essentially acts as a help button, leading you to related documentation on the specific topic.

Each of the case check rules are described in the following sections:
