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.
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!
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!
Thank you for putting out the best Ansys tutorials on youtube, DrDaylo. That being said, please, I need assistance on acoustics simulation (impedance tube experiment) and was hoping you would be able to assist as I've been trying for months now with no significant progress. Thanks
Hey Doc!! Good tutorial....i hope that you'll keep uploading. I'm gonna get you some subscribers. You're really doing a solid favour for the engineers in India.
Your videos are really helpful. Please do a tutorial on concrete beam mid point loading using drucker-prager in ansys workbench. I will be really thankful
@@drdalyo Yes Sir. I tried. First time it got selected and I was able to round edges. But after that I tried multiple times was unable to select any edge.
I am abit confused with the boundary conditions you set at 4:24. Why is there a msg telling you that there is rigid body movement? There is something else which just looks very wrong in the model, take a look at the stresses in the area in which the bolt connections are located. You have tensile stresses there, a bolt cannot pull on the body. I am not very familiar with Ansys but with many other FEM tools so I can only guess what happens here. Ansys automatically sets an independent master node in the center of the bolt and now connects ALL nodes on the cylindrical surface to that one master node. To model this correctly, one has to only connect 180° to the master nodes according to the force direction. I am certain that this structure would completely fail since you can see that there are almost no stresses on the outer parts of the bolt connection. This model would correspond to a glued/welded connection.
Hi! Thanks for your question. Regarding the first point on BC, the message is being displayed because the geometry deforms slightly in the Y direction (out of plane) and there are no BCs to prevent this movement. If you would like the message to dissapear, you could easily insert a Frictionless Support on the large surface of the model to constrain it in the Y direction. Regarding your second question, there is nothing wrong with the model. You have to keep in mind that a bearing load is a simplification and if you want something more accurate you would need to model the bolt itself and apply contact. I think actually you dont understand the loading condition presented. Its a bit hard to explain, but have a look at the image here: apolloedgeblog.files.wordpress.com/2016/09/slide24.png In this case you would have tensile stresses on the bracket. Ansys does not set master nodes at the center of the bolt, and you do not need to connect 180deg. I suggest reading the help information regarding Bearing Loads. When selecting the full interior surface of the hole, the load will be distributed on the compressive side. The structure would not fail because the stresses remain below the yield stress of steel (80MPa < 250MPa).
Hello again, thank you for the first answer, that makes sense but I still have a problem with the second part. The picture actually shows why your boundary conditions are not correct. Take a look at this model: imgur.com/PY8ywD5 espeically the top left region. The stresses are way higher on the left side of the bolt, which is what you would expect from such a construction. In your model the stresses are 0 in that region. If you look at the picture you linked, the top bar is getting pulled to the left. Where would it fail? Ofc it would fail on the right side of the bolt while it should be able to displace freely on the left part which is not a given condition in your model due to the fixed constraint all around the bolt area.
@@CurrencyPrime That is a really good point to mention. Stresses should be way more higher on the left side of the fixed points, since it is pulled to the right. But, in the model we do have a opposite... I think boundary conditions do not reflect the real case.
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 ;)
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 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.
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?
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 :)
Isnt the ring around upper hole a bit too thin? If it was connected wirh bolts or something most of contact would be around the side of ring that is the thinnest?
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?
Hi, in Ansys 2021, I'm not able to extract the results of Topology optimization to a new solution, if I do that, I'm not getting the "geometry" part of the static stuctural process. My requirement is to extract the topology optimized result to parametric software so I can edit it on my own. Can someone please help?
Hello, I am a mechanical engineer, and I wanted to thank you for your RUclips channel which is an anthology of digital simulation. I am contacting you because I have a question regarding a feature of Ansys Workench, more specifically, the static calculation. In particular, I would like to know if it is possible to define a load (force or pressure) which depends on both x and y, a function with several spatial variables. And if you've ever made a video about it, I'd be interested in viewing it. Regards
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
Hello Dr. Daylo, I optimized a component but solver has also removed material between loads and boundry conditions. now some fixed BCs are not attached with load point. what I do now?
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?

Hello Dr. Daylo, I optimized a component but solver has also removed material between loads and boundry conditions. now some fixed BCs are not attached with load point. what I do now?
By comparing previous model stress value increased..then what is the purpose of topology optimization?
If i remember correctly the stress may have marginally increased. So the real savings is weight of material.
Awsome Work
