You can delete a mesh in Abaqus by selecting specific options from the main menu bar, depending on whether you want to delete the mesh for an entire part, a specific instance in the assembly, or a selected region.
Deleting a Mesh in Abaqus
To remove the finite element mesh from your Abaqus model, utilize the menu options available in the main menu bar. The process is straightforward and gives you flexibility in deciding the scope of the mesh deletion.
According to the Abaqus documentation, to delete a mesh, select either Mesh Delete Part Mesh, Mesh Delete Instance Mesh, or Mesh Delete Region Mesh from the main menu bar.
Here's a breakdown of the options:
- Mesh Delete Part Mesh: Use this option to delete the mesh associated with the original part definition. This is useful if you want to re-mesh the entire part in its original context.
- Mesh Delete Instance Mesh: If you have multiple instances of a part in your assembly, this option allows you to delete the mesh specifically from a selected instance without affecting other instances or the original part mesh.
- Mesh Delete Region Mesh: This provides the most granular control, allowing you to delete the mesh only from a specific selected region within a part or part instance. This is helpful for local re-meshing efforts.
Important Note: Deleting a mesh does not cause the underlying seeds to be deleted, so you can modify the seeding pattern and regenerate the mesh. This means your defined mesh controls (element type, seeding density, etc.) remain, allowing for quick re-meshing after adjustments.
Steps to Delete a Mesh
- Navigate to the main menu bar in Abaqus.
- Click on the Mesh menu.
- Select the Delete submenu.
- Choose the appropriate option based on your need:
- Part Mesh (for the whole part)
- Instance Mesh (for a selected instance in the assembly)
- Region Mesh (for a selected geometric region)
- If prompted, select the specific part, instance, or region whose mesh you wish to delete.
This process effectively removes the finite elements from the selected entity, preparing it for re-seeding and re-meshing if necessary.
