Topology Optimization Different Results

Anıl Türkseven

Hi; I created geometry and ı wanted to create new topology geometry, but I got a mistake. My parameters;

-20*20*20mm Cube (Bottom and top have one mm thickness nondesign area so design area is 20*20*18)

- Material Inconel 718 ( E=168000, Yield Strength=980Mpa, Tensile Utilize Strength=1232 Mpa)

- Bottom surface is SPC, Top surface is uniform pressure (30Mpa)

Topology Optimization Setup;

- Stress Contain: 515Mpa (Safety Coefficient 1.9)

- Min Compliance

-Max Vol. Frac 0.4

I want to get at the image (c) geometry.

Can you help me?

Hi Anil,

Typically I wouldn't apply both a stress constraint and volume fraction constraint on the same model.

Try these setups:

Minimize Mass with the stress constraint

or

Minimize Compliance with Volume fraction constraint

Thank you, Zagorski. I have a new question How can I change element density. I don't want see intermediate value. I want to only see 0 or 1. And last question; How can I see threshold value for topology optimization. Thank you very much again, best regards.
