Improved Bonded Formulation

The accuracy of results for static, frequency, and buckling studies is improved for geometries that have bonded interactions. Improved algorithms that mesh bodies independently drive this improvement.

For simulations with bonded interactions between geometries, you can observe solution improvements in these cases:
  • Gaps or small interferences exist between the independent meshes of geometries that are bonded, even though the actual geometries have no clearances (solid-to-solid, shell-to-shell, and solid-to-shell bonded interactions).


    The gap between the two cylinders represents the shell thickness (inner solid body, outer shell body). In reality, the two cylinders are touching with no clearance.
  • There is a physical clearance between bodies that you want to bond.
  • For frequency studies, detection is accurate for the six rigid-body modes for unconstrained assemblies.
  • For assemblies that experience rigid-body rotations, detection is accurate for a nearly zero stress-state
