33.9.1 Mesh Method Settings Dialog Box

The Mesh Method Settings dialog box allows you to apply settings for the smoothing, layering, or remeshing methods.

Smoothing   contains parameters to be specified for the smoothing mesh update method.

Spring Constant Factor   controls the spring stiffness.

Boundary Node Relaxation   specifies how the node positions on the deforming boundaries are updated. This applies only if your model contains deforming boundaries.

Convergence Tolerance   controls the smoothing convergence.

Number of Iterations   specifies the number of iterations.

Layering   contains parameters to be specified for the layering mesh update method.

Options   specifies the criteria for splitting or collapsing cell layers.

Height Based   specifies that the cell layers are split or merged based on height.

Ratio Based   specifies that the cell layers are split or merged based on ratios.

Split Factor   specifies the value of $\alpha_s$ in this equation in the separate Theory Guide. It controls the height or ratio at which the cells are split.

Collapse Factor   specifies the value of $\alpha_c$ in this equation in the separate Theory Guide. It controls the height or ratio at which the cells are collapsed and merged into the next layer.

Remeshing   contains parameters to be specified for the remeshing mesh update method.

Remeshing Methods   contain options that control remeshing.

Local Cell   allows you to remesh deforming boundary cells.

Local Face   allows you to remesh deforming boundary faces. This option is available for 3D cases.

Region Face   allows you to remesh a region.

2.5D   enables the 2.5D model. This option will appear only for 3D cases. See Section  11.3.2 for more information on ANSYS FLUENT's 2.5D model

Parameters   contains parameters that control remeshing.

Minimum Length Scale   specifies the lower limit of cell size below which the cells are marked for remeshing.

Maximum Length Scale   specifies the upper limit of cell size above which the cells are marked for remeshing.

Maximum Cell Skewness   specifies the desired maximum skewness for the mesh.

Maximum Face Skewness   specifies the desired maximum skewness for the surface mesh. This option is active, when Local Face is selected under Remeshing Methods.

Size Remesh Interval   specifies the interval in time steps for remeshing based on the above size criteria only. Marking of cells based on skewness occurs automatically at every time step when Remeshing is enabled.

Mesh Scale Info...   opens the Mesh Scale Info dialog box, in which you can view the statistics of the mesh such as minimum and maximum length scale values and maximum cell and face skewness vales.

Use Defaults   resets the remeshing parameters to the default values.

Sizing Function   contains parameters that control the sizing function.

On   allows you to enable or disable the sizing function.

Resolution   sets the resolution for the sizing function. See Section  11.3.1 for more information. This item will appear only if Sizing Function is enabled.

Variation   specifies the value of $\alpha$ in this equation in the separate Theory Guide. This item will appear only if Sizing Function is enabled.

Rate   specifies the value of $\beta$ in this equation in the separate Theory Guide. This item will appear only if Sizing Function is enabled.

Use Defaults   resets the sizing function parameters to the default values. This item will appear only if Sizing Function is enabled.
