You can enter the Mesh module at any time during an ABAQUS/CAE session by clicking Mesh in the Module list located under the toolbar. Upon entering the Mesh module, the ABAQUS/CAE interface changes in the following ways:
The Seed, Mesh, Feature, and Tools menus appear on the main menu bar.
The Object field that appears in the context bar allows you to display either a part or the assembly.
ABAQUS/CAE may change the color of each part instance in the assembly displayed in the viewport. These color cues describe the meshability and dependence of each instance. Independent instances appear in a color that describes their meshability, while dependent instances appear blue in the Assembly context and white in the Part context. See Meshing independent and dependent part instances, Section 17.3.6.
To exit the Mesh module, select any other module from the Module list. You need not save your mesh before exiting the module; it will be saved automatically when you save the entire model by selecting FileSave or File
Save As from the main menu bar.
