You can delete meshes throughout entire parts, part instances, or just within selected regions. To delete a mesh, select either Mesh
Delete Part Mesh, MeshDelete Instance Mesh, or MeshDelete Region Mesh from the main menu bar.
Note: Deleting a mesh does not cause the underlying seeds to be deleted, so you can modify the seeding pattern and regenerate the mesh.
To delete a mesh:
From the main menu bar, select either MeshDelete Part Mesh, MeshDelete Instance Mesh, or MeshDelete Region Mesh.
ABAQUS/CAE displays prompts in the prompt area to guide you through the procedure.
Tip:
You can also delete meshes using the 
or 
tools, located with the mesh tools in the Mesh module toolbox. (For more information, see “Using the Mesh module toolbox,” Section 17.13.)
Do one of the following:
If you are deleting a mesh from a part, click Yes from the prompt area to confirm that you want to delete the mesh.
If you are deleting a mesh from the assembly, select the instances or regions from which to delete the mesh. Click mouse button 2 to indicate that you have finished selecting. (For more information on selecting objects, see Chapter 6, “Selecting objects within the viewport.”)
ABAQUS/CAE deletes the mesh.
