Importing External Mesh Files. Now, when you open Mechanical independently, you can import LS-DYNA Input (.k and .key), or Abaqus (.inp) files directly into the application using the Add Model Import option available from the Geometry Imports object.

Body Merge. A new Body Merge object allows you to combine multiple geometric bodies with shared faces into a single merged body. The mesh is also merged if the model has been meshed. Body Merge simplifies complicated geometries by reducing the number of bodies in a model, which is useful when working with complex parts. It can also be used to merge bodies that were previously sliced to generate a hex dominant mesh.
