Interpretation of Topography Optimization Results

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

Figure 1 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: 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).
