Preparation of Geometry
Brackets – Metallic and Composite
Generation of Midsurfaces
- Advanced tools for midsurface manipulation
- Connect Midsurfaces
- Convert radii to corners
- Automated property definition
- Using the midsurface option
Hypermesh ‘keeps the thickness in
mind‘ and can assign it automatically
to the elements

Input / Output
- Comments and entries that are not known
by Hypermesh are kepf in the .bdf
- are moved to the end of the file
- .bdf files become very large due to
Hypermesh comments
- can be swiched off in V10
Components from geometry file
- Components are automatically generated
- By Hypermesh comment
- By Property
- By One component
Sustain file structures
- Include structure can be conserved
Property IDs
- Division Hypermesh ID / Solver ID
- may be different
- may lead to user errors
