OSSmooth is a semi-automated design interpretation software, facilitating the recovery of a modified geometry resulting
from a structural optimization, for further use in the design process and FEA reanalysis.
Topology optimization results are interpreted to provide an iso-density surface based on the volumetric density information
of a topology optimization, which is conducted using OptiStruct.
FEA topology for reanalysis provides an iso-density surface based on the volumetric density information from a topology
optimization. Through tetrameshing for 3D models and inheriting boundary conditions, the results from FEA topology can
be used for quick reanalysis.
The FEA topography option in OSSmooth allows the results from an OptiStruct topography optimization to be interpreted as one or two level beads and recover boundary conditions upon geometry extraction.
An option for iso surface is also provided for combined use, which performs the same functionality as FEA topology, with
FEA topography.

The autobead feature of OSSmooth allows OptiStruct
topography optimization results to be interpreted as one or two level beads.

shows the level of detail captured in both cases; while the 2-level approach captures more
details, it is more complicated to manufacture than the 1-level interpretation, often
without significant performance gain.
Example: Autobead Result from Topograph Optimization
Example: 2-Layer Autobead Result from Topography Optimization
Some topography performances are relying on the half translation part. OSSmooth can
interpolate topography optimization results to 2-layer autobead (autobead third argument
2).
