33.6.5 Profiles Dialog Box

The Profiles dialog box allows you to define new profiles by reading cell zone and boundary profile files. You can also examine the existing profile definitions and delete unused profiles. See Section  7.6 for details about cell zone and boundary profiles.



Profile   contains a selectable list of available profiles. When a profile is selected its available fields are displayed under Fields.

Fields   displays the fields available in the selected profile. After the profile file has been read, these fields will also appear in any boundary condition dialog box (e.g., the Velocity Inlet dialog box) that allows profile specification of a variable. To the right of (or below) the variable in the boundary conditions dialog box, there will be a drop-down list that contains a constant and the fields from available profile files. To use a particular profile field, just select it from the list.

Interpolation Method   allows you to select the interpolation method for the profile selected from the Profile list. This selection is only available for point profiles, and will only take effect when the Apply button is clicked. The choices include the following:
Constant   specifies that ANSYS FLUENT should use zeroth-order interpolation to assign the point profile values to the nearest cell faces at the boundary. This is the default selection.

Inverse Distance   specifies that ANSYS FLUENT should assign a value to each cell face at the boundary based on weighted contributions from the values in the point profile file. The weighting factor is inversely proportional to the distance between the profile point and the cell face center.

Least Squares   specifies that ANSYS FLUENT should assign values to the cell faces at the boundary through a first-order interpolation method that tries to minimizes the sum of the squares of the offsets (residuals) between the profile data points and the cell face centers.

Delete   deletes the selected profile from memory.

Orient...   opens the Orient Profile dialog box, in which you can reorient and scale the profile. This item appears only in 3D.

Read...   opens the Select File dialog box (see Section  2.1.6) so that you can read a boundary profile file. If a profile in the file has the same name as an existing profile, the old profile will be overwritten.

Write...   opens the Write Profile dialog box, in which you can save profile data.

Apply   sets the selection made in the Interpolation Method list for point profiles in preparation for interpolation. The profile is not actually interpolated until a profile field is selected in a boundary condition dialog box (e.g., the Velocity Inlet dialog box) and the solution is initialized.
