SpaceClaim v18.1 Final Geometry File: cutt.ly/DrDalyO-Topology-SYS2...
Mirror Link: goo.gl/Nj57Ns
Long Description:
We will begin by opening ANSYS v18.1 Workbench interface. Check the engineering data to ensure the proper material is selected (in our case it will be the default material). Open up SpaceClaim to create our geometry (note, you can always right click on the geometry cell and click to open in DesignModeler instead if you are more comfortable using it). Once in SpaceClaim, we will use the line tool and pull tool to create our metal bracket. Once created, we exit SpaceClaim and head into Mechanical to set up our loads and boundary conditions. Create a mesh using the sizing "Proximity and Curvature" to better capture the round corner details. Add two cylindrical supports, choose to make the tangential component free. Add one bearing load with 50KN in the X-dir and 100KN in the Z-dir. Add Equivalent Stress results and Solve to view the stress results.
Exit Mechanical and go back to the project schematic window. Drag Topology Optimization onto cell 7 "Results" of the first analysis. This will link the static structural analysis to the topology optimization analysis. Leave most of the settings default. Change the Response Constraint to retain 60% of the mass. Solve the system.
Exit out of Mechanical and right click on cell 7 Results on the topology optimization analysis and click on "Transfer to Design Validation System" in order to export the STL file generated into a new static structural analysis automatically. Open up SpaceClaim in the new analysis to view the STL import results. Create a new sketch plane and copy the edges of the STL file to a new sketch. Under the Repair tab, use the option Fit Curves to simplify the rough curve geometry from the import. Choose to Correct Tangency and keep the default distance 0.1mm. Simpify the rest of the geometry as needed using the Trim Away tool and Create Corner tool. Should you want to reduce the amount of faces for mesh generation, use the Merge Faces tool under the repair tab to merge selected faces into one face. In order to not export all product structure files into the analysis, we must right click on the products in the structure tree and choose "Suppress for Physics" in order to remove these items from the analysis. Keep only the Solid file.
Exit SpaceClaim and open Mechanical by double clicking on the Model cell. Say yes when prompted to read upstream data. Regenerate mesh and reapply boundary conditions and loads. Finally solve the model to view the final results.

You are literally a king. I'm sick and tired of these ansys videos recorded in 360p with shitty royalty free music playing and no audio commentary. You made this very straight forward.
This is by far the best ANSYS video out! Great work DrDalyO!
Please continue creating content for the latest versions of ANSYS - you are helping so many people. Thank you!
You're an angel, thank you for showing us how to do this in a simple and straightforward manner.
Dr. DalyO, I really appreciate the time that you have spent to put these ANSYS tutorials together. They are by far the most informative, concise, and interesting modeling/FEA videos that I have seen. Most videos are either technical or interesting, but not both - you have an excellent method of presenting. Thank you! I see that most of your videos are from 5 and 6 years ago. I am really looking forward to you releasing more tutorials based on ANSYS 2020. Please keep the great work coming!
Thank you very much!! I will keep posting!
This was extremely helpful. You did a good job of walking us through the steps
thank you so much for this great tutorial.

+El Makkaouy Mohamed Thank you!
You are amazing man :)
Continue making tutorials please
Really need a Topology Optimization tutorial for COMSOL
Hi DrDalyo, thanks for the awesome tutorial. However, i did face a problem while transferring the optimized results to a new static, structural system. When i update the geometry in block 'c' it gives me this error "Update failed for Geometry component in Model,static, structural . Update of the geometry component in Model, static, structural did not mark the component as updated due to a change made to the Results component during the update". This may be a noob error on my part but I would really appreciate any comments from you on this.
great work man loved it :)
Thanks!
Extremely helpful tutorial, thank you so much! Just wanted to ask, when tapping Transfer to Design Validation System (Ansys 2022 R2) , has anyone else faced the problem that there was no geometry in the cells to edit?
Thanks for the video sir,
How to topology optimization without reducing material thickness? Are there any steps to do this?
thank you sir
Will you upload a new Ansys tutorial soon? Been nearly 3 years from the last one.
Hi, excellent video. Do you know if is it possible to do a topology optimization from initial stresses calculated previously in Ansys APDL, instead of applying a pressure in Workbench? Thanks
Great video!
Could you do some more tutorial videos with Ansys 18? Or do you know of any websites that is good?
I'm trying to learn the software for the first time, but videos of older version like 17 or lower have quite a different user interface which makes it difficult to follow when using version 18.
very helpful
Thank you. Please make new videos also in ansys
Hello Doctor, Nice video.
Sir can you please do a tutorial on "how to find heat dissipation of a brake disc" for optimising the vents on the disc for better heat loss
Great job ! Thank you a lot.
Thanks!
Thanks for the upload
No problem!
Thank u so much Brother
well done, thank you
+Abbas Kasim Mohammed Thank you!
Awsome Work
I need a Favor from you we have studied the residual Stresses in casting now we want to optimize the shape of Casted part to minimze stresses,how can we do this?
Hi thank you for great video. I have a question when comparing with tabular data. before applying topology Stress.Max is 83.5 but it grows 137.49!! I wanna know of purpose of Topology Optimization! Thanks :)
Great details.. thank you sir
Thanks!
very useful... thanks
Really thank you sir!
+Have a nice time! Thanks!
Hello sir please made a tutorial on how to do fea analysis of knee joint
Hello! Thx for your video.
I have a question . Is this a linear structure??
Great Job!!
hello, i need help finding the size function on version 19 r3. anyone that can help would be very greatful.
greatly done. thank you
thanks!
awesome tutorial
Thanks!
thank youuu for this video
Welcomeee!
Thank you so much.. !!
For some reason I don't have Size Function Option, I only have Use Adaptive Sizing. Yes/No Great video!
Is there any way to do something similar on R16? Thanks in advance, great quality video.
Hello sir, thanks for the video, it is very useful. However, i'm trying to create an optimization for a composites sandwich structure, but when i click solve on the solution(b6) for optimization, the software gives out a message "imported layer is not allowed in the analysis".
Is there any way this can be overcome? or perhaps you can suggest alternative ways I can optimize composites in Ansys workbench.
Currently I'm using Ansys workbench student version 19.2
Great , thanks
Hi! can you help me with the issue that i can't transfer my topology optimization data to another geometry or static structural module?
nice job, thank you
Thanks!
Thank you for this great video. I have a problem, and I really hope you can help me: once done the topology optimization, I click on "Transfer to Design validation system" (8:41), I obtain another Structural system, I update the results of the topology optimization system, and the geometry of the new structural system, but in this moment I get the errors "(DP 0) Attach failed.", "(DP 0) Geometry Interface not found.", "(DP 0) No compatible interface found for this file type".
Do you have any idea of what cause this problem?Thank you very much in advance!
Hello Doctor, can we export optimized desing as .stp or .igs or .xt file? So we can re-design by different cad softwares
Hi Doc, Plz share the download link for ansys work bench for a lower configuration laptop.
Great video! Could you think of doing some similar video explaining the topology optimization with a modal analysis instead of the static structural? I would be very interested ;)
would be a good idea. I will see if i have time.
thanks alot
Can I ask a question? I did it according to the video, but why i have only one original model rather than 1 original and 1 optimization model in the Geometry of transfer to design validation system. I donot know if I state my question clearly.
this looks very much like DesignSpark Mechanical!
hello doctor, i am performing topological optmization for 2d truss structure and am able to perform static structural analysis perfectly. But, for topological optimization, i am not able to use line body for optimization even though i have given a circular cross section area for the body. can you suggest any possible reason for the same?
Amazing !!! really thanks
Np Thanks!
Which method of topology optimisation is used here like SIMP, BESO , level set or ESO? Actually i want to know at the backend of Ansys, which algorithm is used. Basically, i want to perform topology optimisation in a coding environment especially in python, so some information is required regarding this. Also, can we check the backend algorithm used in Ansys? Hope to hear from you soon.
Great video man. I am however struggling on how to an optimization for the displacement and mass. The displacement response convergence graph shows that the displacement stays zero which results in a non-convergence error. The mass criterion converges fine. Any ideas?
+Conner Howie Not sure i fully understand, maybe send me a more detailed email.
sir plz help
thiz kind of error comes in ansys 14
You have a bearing load that has an axial component. This is not allowed. If an axial component is desired, create a separate force load in order to apply the axial component.
One or more bodies may be underconstrained and experiencing rigid body motion. Weak springs have been added to attain a solution. Refer to Troubleshooting in the Help System for more details.
Try adding a frictionless support on the two large faces of the bracket.
What about the option "manufacturing constraints"? Which are those and how do they work? Thx
