I am running topology optimization on a structure previously analyzed in static structural and the setup is shown below. The cylindrical supports are fixed in the radial and axial directions.

In details of the result(topology density), check the "retained threshold" property.
For details, check :
Topology Density (ansys.com)
from help: Retained Threshold: This property is controlled by a slider that represents the range from minimum to maximum for the result. The default value is0.5. The supported range is0.01to0.99(greater than zero and less than 1).
Once you evaluate the result, use the slider to view the optimized topology in the graphics view. The application computes and displays the values for the Original Volume, Final Volume, Percent Volume of Original, Original Mass, Final Mass, and Percent Mass of Original properties.

Hello,

I dont have Retained Threshold on my Ansys Mechanical R2023 R2. How could i make it appear?

Regards

Does the retained percentage in the initial setup mean anything for this? I tried to shift the retained threshold as you mentioned and that marginally improves the remaining structure. This leaves a few more small pieces floating in space, but not too much detail. I think the optimization is still removing too much material and the default results in only the regions of exclusion.
