Hello sir, I am a master’s student and I am researching this topic topology optimization and I need your help and your lectures regarding the topic in pdf format. Thank you in advance
Dear sir I have some questions For a program like Ansys does it perform the sensitivity analysis under the hood? If no how can one perform a sensitivity analysis? Does it have to be done after validation? What are the variable that can be changed for truss optimisation problem? What do you mean by density as variable? Thanks in advance
Many CAE programs such as Ansys and Solidworks provide the functionality of topology optimization. I would be very surprised if they don't perform sensitivity analysis in optimization. "What are the variable that can be changed for truss optimisation problem?" In truss optimization, the design variable is typically the radius. When the radius becomes zero (or a very small value), it means that the corresponding truss is not needed. "What do you mean by density as variable?" I meant a pseudodensity, not the physical density of the material. The pseudodensity (0 or 1) indicates whether there is material at the element.

How do you preserve the outer layer only when doing topology optimisation?

May you make video on how to make compliant mechanism with topology optimization.
I'm not super familiar with this, but there are now videos about that online 👍
Is "Infill Optimization for Additive Manufacturing -Approaching Bone-like Porous Structures" the right paper?
yes, the results are from the infill optimization paper.
Sir can we covert the 2D optimised infill figure to CAD file?
