Adding, Editing, and Building Meshing Sequences
When you add a new Component to the Model Builder, a meshing sequence is added by default in the node Mesh 1. You can add more meshing sequences to the Component by right-clicking the Component node and selecting Mesh. When a Component has more than one meshing sequence, they are collected under a Meshes node. To add new meshing sequences to such a Component, you can alternatively right-click Meshes.
You create a mesh by building a meshing sequence, which contains a number of meshing operations as nodes in the sequence. For the default physics-controlled meshes, the software sets up the meshing sequences automatically.
For Mesh nodes created using adaptive mesh refinement, see Meshes Generated by Adaptation.
Adding Mesh Nodes
Right-click a Mesh node () in the Model Builder and then select an option from the context menu. Enter the properties in the Settings window. In numerical fields you can enter expressions that contain global parameters.
Building Selected Mesh nodes
To build all nodes (if needed) from the first up to the selected node:
•
In a Settings window, click the Build Selected button ().
•
Right-click a node under the main Mesh node and select Build Selected. Or click the node and press F7.
•
Windows users: In the Home or Mesh ribbon toolbars, click Build Mesh.
•
macOS and Linux users: In the Model Toolbar or the Mesh Contextual Toolbar, click Build Mesh.
Build All Mesh Nodes
To build all nodes in the meshing sequence (if needed):
•
In a Settings window, click the Build Mesh button ().
•
Right-click the main Mesh node () and select Build All. Or click the Mesh node and press F8.
•
Windows users: In the Home or Mesh ribbon toolbars, click Build Mesh.
•
macOS and Linux users: In the Model Toolbar or the Mesh Contextual Toolbar, click Build Mesh.
Editing Mesh Nodes
To edit a mesh node, select it in the tree, and make changes in the Settings window that appears. Nodes that you have edited display with an asterisk (*) at the upper-right corner of the icon () in the Model Builder. The following nodes are marked with a yellow triangle at the lower-right corner of the node’s icon to indicate that they need to be rebuilt. To see the result of your edits in the graphics, use the methods described above to either Build Selected or Build All nodes.
