Description: Merge operations for geometry objects have always preserved loads, boundary conditions, and section assignments. Now when you merge mesh objects or create mesh parts, Abaqus/CAE copies, modifies, or otherwise maintains the sets and surfaces in the model such that the loads, interactions, and other items are preserved in the same way as they are for geometry.

When you create mesh parts from geometry, Abaqus/CAE copies and converts the contents of geometry sets and surfaces as needed and applies them to mesh locations equivalent to the locations on the original geometry. For example, vertices are converted to nodes, and edges are converted to a combination of nodes and elements.

When you create a mesh part from assembly instances, you can choose to suppress the original geometric instances and replace them with the new mesh part instance. The loads, boundary conditions, section assignments, and reinforcements are all applied automatically to the mesh part through the converted sets and surfaces. If you choose to switch back to the geometry, the sets and surfaces still contain the geometric content (vertices, edges, and faces), so the loads, boundary conditions, etc. are still maintained.
