Great video! I'm looking to improve the performance of a heatsink with a similar method. Do you know if there is any way to set temperature as a target?
Excuse me, may I ask why the results obtained by following the steps in the video are strange.... (if it is possible , maybe I can send my result by Gmail )
Your maximum stress is 882 MPa, but the yield strength of steel is much less than that. Are your values extremely high because you placed the force on a line (i.e. the forces are not distributed over an area)? Thanks!
It is an L shape and there is a so called singularity in the corner, where the vertical and horisontal regions meet. (Sry, I can't describe it better, you can see the singularity or hot spot at @6:11 on the edge with green) It comes from math and the value displayed is actually "incorrect". If you use finer mesh, you can see, that the region with the outstanding high stress is only a thin line. You can get the correct stress values with 2 methods. 1st you can apply some rounding on the sharp edge, like 2 mm or 2nd, you just apply a fine mesh and read the values of the neighboor element. In this case the highest stress should be around 170-200MPa.
Hello, could you please tell me how to do all this things from 13 minute 55 second of your video if i have 3D model and not planar like you? How to draw 3d sketch and fix those irregular lines like you did in 2D sketch? Please help me, it is for my school project. Thank you very much :)
great work,really appreciate your help.kindly upload part 2.
your equivalent stress was 39 MPa but after Lattice Optimization equivalent stress is 349 MPa, what does it mean ?

Which version is this please tell

i had the same problem
The geometry is strange in new version, but i can solve the problem with version 2024.

@@herkdaniel807 Thanks Daniel for this explanation, I was confused because when I refine the mesh, the maximum stress increases !!
hello, I want to know why it takes the maximum deformation less than 0.3 ? how do you find the value 0.3 !
It is a problem from the textbook. Less than 0.3 is the objective of the problem.

After the topology process, you can export the geometry into other cad that is esier than Ansys
Greetings, part 2 where can I find it? Excellent video
I haven't gotten time to record it. Will do it when finding time.
name of the version
Which version is this
2019
