Displaying the Mesh Model
After you mesh a FEM model, Creo Simulate treats the model as though it has two separate objects to display—a geometry model and a mesh model. The geometry model includes the geometry itself as well as the properties and entities associated with the geometry. The mesh model includes the mesh as well as any attributes of the mesh.
The following Simulation Display options control how geometry is displayed and models are meshed:
Mesh and Model check box on the Mesh tab.
No Mesh option from the Mesh Display Mode drop-down menu
You can use the Mesh and Model check box on the Mesh tab of the Simulation Display dialog box to display both the geometry and mesh models while you are working with functionality in which only the mesh model is active. This prevents portions of your model from disappearing from the screen if you remove a mesh. Here are the situations in which only the mesh model is active:
Immediately after you create a mesh
When you are refining a mesh using Home > Mesh > Improve
When you are reviewing a mesh using Home > Mesh > Review
When you are deleting a mesh using Home > Mesh > Erase
When you are running an analysis
When you are viewing results
You use the No Mesh option to turn off the mesh line display. Regardless of how you set the Mesh and Model check box, you can only use the No Mesh option when both the geometry and mesh models are active in the overall model—for example, when you add properties, loads, constraints, and so forth. You cannot use the No Mesh option if only the mesh model is active.
