Body materials based on bodies/components:
• Typical approach w/geometry decomposition
• New approach w/geometry decomposition via component
Each component comes across as
a body to Mechanical
Each decomposed
body is separate in Mechanical
Often geometry is sliced in order to get sweepable regions for
meshing, but the material should be the same.
New in 2021 R1, a user can specify that materials follow
component grouping rather than body grouping.
New Option
