About Mesh in Topology Optimization
Before you can run an optimization study, you must generate a finite element mesh for the model, or open a saved mesh:
• To generate a mesh, click
Home >
Mesh to generate a mesh for the model.
• To open a saved mesh, click Home > Mesh > Open FEM Mesh.
In Creo Topology Optimization, you can only open a mesh that was created in Creo Topology Optimization, because mesh can only be opened in the same application in which it was generated and saved. You cannot open a mesh that was created in Creo Simulate FEM mode.
Use the items in the Mesh group to generate, control, and check a mesh. Before you create a mesh, this group contains the following active items:
• Home >
Mesh—Starts the generation of the mesh.
• 
Control—Click the arrow next to this button to open one of the mesh controls. Use this dialog box to create mesh controls. Mesh controls determine things like the size of the elements, or numbering of nodes and elements.
• Home > Mesh > Open FEM Mesh—Retrieves a saved mesh.
After the system successfully generates a mesh, the following buttons become active on the Mesh group:
• Home > Mesh > Improve—Attempts to improve the mesh. When you select Improve, the system asks you to enter the number of additional passes you want for mesh shape improvement. After you enter the number of passes, the system tries to improve the shape of solid and shell elements and redraws the model.
• Home > Mesh > Check Elements—Opens the Element Quality Checks dialog box so you can check element quality.
• Home > Mesh > Review—Opens the Review Mesh tab so you can review meshes, nodes, or elements.
• Erase—Erases all or individual meshes in the current model from the memory. This command only erases the mesh from memory. The Erase command does not erase saved mesh files from disk.
• Home > Mesh > Save FEM Mesh—Saves the mesh for the model.
You can work with mesh in the Creo Topology Optimization environment.
For information about mesh, see topics in the Creo Simulate help. Some functionality in Creo Simulate, might not be available in Creo Topology Optimization.
