This panel is used to set local mesh densities, either finer or coarser than the global mesh density, in selected areas of the part. To access this panel, click 
().
As you select entities in the model, they are listed in the window on the left side of the panel. You can configure the mesh density for each entry individually by first selecting the entry and then adjusting the value on the right. Higher level entities are also broken down into components, for example, the individual curves of a region are displayed as subentries of the region. This means that you can set the mesh density for specific sides of a region.
- An imported STL model will appear as a single entity so it is not possible to define local mesh densities directly to the STL model. You can however use the Create Regions mesh tool to create regions from the STL model and then define local mesh densities to the region entities.
- You can click directly on the model to automatically select multiple elements that belong to a face or body, depending on the selection priority you set initially. For example, you can select multiple faces and edges of a body, or multiple edges of a face.
Dialog elements
- Explorer view
- Displays all entity values that are selected on your geometry model. For example, a surface is displayed as +...(S) followed by its surface number.
Click the plus sign to reveal an expanded view of smaller entities such as curves.
- Global mesh density
- Allows you to specify a global mesh density to be applied to the model as a whole.
- Global edge length
- Enter a target mesh size. This value is then applied globally to the entire model, where each node is separated by the specified edge length.
- If the option Use global edge length is selected in the Mesh density of selected entity area, and you select a specific entity to change, the Global edge length is used.
- Mesh density of selected entity
- Allows you to specify target mesh sizes either globally or locally for the selected entity, for example surface, curve, or region, in the window on the left.
Entities you have selected on your model will appear in the Explorer pane to the left. Select an entity from the Explorer pane, and then choose either Use global edge length, or Local target edge length and enter the required value, and click Apply.
- Use global edge length
- Allows you to specify a global edge length for the selected surface or curves.
- After selecting a surface on your model, then selecting an entity in the Explorer pane, this option is selected by default. The Global edge length then aims to separate each node by the specified value after clicking Apply. Tip: Deselect this option to use the Target edge length option.
- Target edge length
- Specifies the Target edge length value to be applied to the selected entity.
- The selected model entities will appear in the Explorer pane. Select an entity from the Explorer pane, then enter the required local mesh target edge length value and click Apply.
- Target number of divisions
- Once you have selected a curve, use this option to specify the number of segments you would like to divide the curve into.
- For example, if you have a curve of 120 mm that you want to divide into 10 segments, you will end up with 10 curves of 12 mm each. Note: The Target number of divisions box and the Target edge length box are mutually exclusive, and automatically adjust each other.
- Local mesh density quick change
- Click on the arrows to change the local mesh density quickly. The up arrow doubles the mesh length; the down arrow halves it. Note: The up and down arrows automatically apply the changes you make, so you do not need to use the Apply button.
- 3D meshing attributes
- When setting the local mesh density, allows you to set the parameters related to 3D meshing.
- Preview interior nodes
- Shows the effect that the local mesh density setting will have when the model is meshed.
The preview shows the predicted position of nodes interior to the selected entity and so will give a good indication of the resultant mesh density.
