Description: You can now edit a model without deleting the entire mesh. In previous releases, Abaqus/CAE deleted any existing mesh when you made a change to model features. Abaqus/CAE now retains the mesh where possible and attempts to attach it to the modified model when you modify or add features. The mesh is deleted locally only in the vicinity of detected changes to the geometry.

Mesh retention also extends to the creation of a bottom-up mesh. You can assign the bottom-up meshing technique to a cell that contains a top-down mesh, and the existing mesh and associativity are retained, allowing you to add a bottom-up mesh without starting over.

For smaller enhancements, such as changing the diameter of a hole or other minor dimensional changes, retaining the mesh can save a great deal of time over creating a new mesh. For model changes that more significantly impact the mesh, you may want to delete the mesh so that Abaqus/CAE does not unnecessarily expend resources attempting to reuse the existing mesh.
