Most of the material in this channel deals with a narrow Engineering/CAE aspects of the Catia v5 and its reincarnation as an APP in the 3DEXPERIENCE platform. Generally speaking, this stuff is covered in courses that I teach in the University of Windsor at different levels. There are some miscellaneous topics which have also been uploaded.

That seems to be a software bug and not the desired software behaviour. Thank you for spotting this, I've reported it to 3DS.
Thank you Alexandre, it took so much of my time.
Hi Professor, awesome video, learnt a lot. One thing I'd like to add is that the user can click on the formula button (at the bottom of the screen). There you can pick the parameters that are associated to the material and modify their value.
@alexandrefernandes6286 Dear Alexandre, I am glad you found it useful.
22:31 how to switch the orientation of the toolbar from vertical to horizontal
quick google search says press shift
I would like to know what's the certification this method has( Faa,Api,Astm)? I never found fatigue studio for resin and fiber can you indicate any?
Sorry, I do not know the answer to your question.
@1:25 How can we trust the calculation if the structure buckles ?
Linear buckling analysis is only a non-conservative estimate. It ignores many things such as imperfections due to geometry, loading, material flaws/ etc. I suggest that we look at a standard book on stress analysis where things are spelled out in more detail.
@@naderzamani5752 thank you for your effort.
Thanks a lot. I was struggling to find the output controls and your video helped me a lot.
Dear Shanny, I am glad that you found it helpful.
I'm learning from the videos you always post. Thank you.
@@eastsub I am glad you are finding it useful.
Excellent video, Sir. Thank you.
I am glad you found it useful.
Thank you for your useful content🌹🌹🙏🙏
I am glad you found it useful.
Professor Zamani, is the course online? Coursera, EdX platform, anything of the sort?
Hello Aleksander, this is a third year summer course for mechanical engineering students at the University of Windsor in Canada.
I have question for you sir. Can we make generic assembly in catia with let's say 3 parts. Part 1, Part 2, Part 3 and activate and deactivate the parts with the help of excel or other means. Thanks in advaance
Dear Armit, my guesss is that you have to, you have to write a "Macro".
You are undoubtedly dedicated to your work related to catia.
Hi sir
Very good job ! Well done and thank you !
I am glad you found it useful.
Hi professor. Is this video part of a MOOC?
No Alexandre, it is for my students taking a first course of Mechanical Vibrations at the University of Windsor. The lectures are at 8:30 am and I am trying to make it easier for those who do not own an alarm clock.
Sorry, I meant a course in "Computer Aided Engineering".
Please explain active body control in car suspensions Sir. Thanks & regards.
Dear MRY, I will discuss your suggestion with "Aghaye Soroush" and we will put something together for this topic.
sharp edge...coarse mesh... mises values may differ significantly
You are absolutely correct. I tell the students about the Pricnciple of GIGI (Garbage In - Garbage Out). I tell them that this is how you do it in the software. The validity of the results depends on many factors that we are not disceting (in this course). They are cautioned that if you ignore those issues and do this kind of work for living, it will not be very long before receiving the pink slip.
I don't think you showed the fourth slide in the Powerpoint.
Ok, I will post it as an announcement on Brightspace. If I forget, please remind me in class.
Pouvez-vous faire svp une video qui montre comment traiter un problème de corrélation numérique entre deux logiciels ?
Dear Zakaria after I have this translated to English، I will try to get back to you. I am not sure what it says.
Ok, I see what you are saying, but do not undestand what you are asking, Can you be more descriptive? Give an example please.
@@naderzamani5752 hey Sir Nader, Thank you very for this intersting content. In fact, i have a subject untitled by '' correlation of crash simulation between Radioss/Ls-dyna for a volumic screw''. If you can a make a video to clarify how deal such type of problem. And tank you for all
Dude you are a saviour! Assembly pattern has been doing my head in for the past couple of days, finally solved it
It's very intersting
Hello Sir, can you make video on composite sandwich ply extraction
Hello! Thank you for this content, it is very hard to find such info! Could you indicate any official documents that relate the positive normal with the top? Thank you again!
I am glad that you find these useful. Unfortunately, things are not well documented.
U CAN use CPP and not use formula
ببخشید استاد من فارسی مینویسم ،من میخوام تو حوزه طراحی و ساخت کامپوزیت و نانو لوله کربن دانش کسب کنم نمیدونم با چه منابع و آموزش هایی شروع کنم
رزان عزیز. رشته اختصاصی من کامپوزیت نیست. تنها دلیلی که این ویدیو هارا انجام دادم بخاطر این بود که تعدادی مسائل ساده کامپوزیت را با کتیا مدل کنم. جواب سوال شما پیش فردی هست که رشته او کامپوزیت هست.
عالیه
Thank you, I am glad you found it useful.
watching this from Wichita State ✌
I am glad you founf it useful.
many thanks to you
I am glad you found it useful.
Hello, your knowledge on this program is incredible, congratulations. I have problem I can't solve: I want to model and analyze a roller pushing on a piece of flat metal sheet. The roller is not moving freely, only moves against a piece of metal sheet fixed on one end, but the roller moves only in the direction towards the metal sheet, not laterally, not transversally. Just pushes on the sheet of metal, but, I can't figure out how to have the roller spin and actually roll on the sheet of metal. Instead the roller gets attached to it between meshes in contact. If I get the roller spin and move along on direction, it seems to work, but it pulls from the metal sheet, which is not correct. I'll really appreciate any help!!! thank you Nader.
Thank you for your kind words. It will be helpful if you had a hand drawn sketch for a better understanding of what is going on. Can send it to me to zamani@uwindsor.ca
Great video sir.
👍
Thanks
Hello again, Dr. Zamani, Could you determine the reactions at any truss members, or assume we have a group of beams acting as a single solid carrying a load? I am interested in finding out the internal forces at a specific section. This information will be very helpful for sizing elements such as bolts or fillet welds in a section.
My question will be for both Catia v5 and Catia 3DX.
Hello hkazzaz, are you referring to (for example) axial member forces in a truss structure?
@@naderzamani5752 Let's say truss structure for now, can we get reaction forces at truss joint , Catia can provide reaction at the fixing but I am interested at a joint as we do when we draw free body diagram for a member
Dear Haidar, I uploaded something that may be what your are referring to. Here is the link. ruclips.net/video/z48EjR-Di4U/видео.html
@@naderzamani5752 Perfect, thank you very much professor
^-^
This is Excellent Uncle but , i Don't care . ( I am poor ) 🥲
I really appreciate this, I am about to go through these as I am about to start a job using CATIA, do you know of any good videos I might look through for doing car surfaces?
Dear "user-tz9fl1yv7r", I am not a CAD person and therefore cannot make meaningful suggestion. Good luck in your new job.
May God’s peace, mercy, and blessings be upon you, Dr. Zamani . a question please. This is a simulation of user-imposed speed and acceleration, not real physical speed and acceleration, right? An example of this is not the cube sliding along an inclined path based on gravity, thank you very much
Hello najinoureddin, yes you are correct this is strictly "kinematics" and does not know where the acceleration is coming from. That is why the workbench in Catia is called "DMU Kinematics". in the versions of Catia burried inside of 3DEXPERIENCE platform, you can also perform kinetics such as block sliding down a ramp under gravity. Here is a demonstraion by Maxine Chagnot ruclips.net/video/mKr6L0J6tjc/видео.html
@@naderzamani5752 Thank you very much for your attention. Yes, I saw the link and the simulation of sliding under the influence of gravity and being affected by the amount of friction, including the rebound resulting from the impact. So we can say that the same command applies to the acceleration command in the analysis workbench for version v5. We cannot drop a mass from a height onto a surface. This is correct ?
Hello thanks for good video. I have a question. Why your contour color was wrong?
Dear greatland317, I had a cheap laptop and the graphics card could not do the diaplay of the rendered stess contour. It does not ordinarily happen.
Hey Prof. Zamani, this is a very good video thanks. I think I may have spotted why you get a different result. Do you apply the radial perturbation load 1.4 N incrementally at the same time the shell is compressed? it should be two steps first step apply only loading until 1.4 N and then you have a shell with a large dimple and in the second step you compress the shell.
Hello Nader thank you for your high quality videos, do you know how to model a strucural steel cable in catia ? My problem is a steel tubular frame of 1m by 1m with diagonals that are steel cables. The frame is clamped at the bottom and the is a load on the left side of the tubular frame. I want a model where only the diagonal cable that works in traction can do some work and the cable in compression instantaly buckles so doesn't work in compression and doesn't trasmit any load
Hello, is there a reason that you don't want to model it as a spring? I am assuming that your concern me be that a spring also resists compression.
Yes I tried with a Spring but it resists in compression so my result are wrong maybe I should run a first analysis and then delete all "compression cables" but maybe you know another method ?
Dear Julien, I will look into it. If I come up with an answer, I will let you know. @@Binette96
Thank you Nader !! I would be trhilled
@@naderzamani5752 Hello Nader, any news on the method ? I found some method to model a rope that takes only traction and 0 compression in solidworks with a Spring model but I can't find any ressources on that topic for Catia this is weird
May u please use switch statement?
Thank you, Professor! I'm glad you found value in my video and took the time to recreate it accurately. Your support means a lot to me.
was very useful thanks so much.
Thanks dear Amin.
Hi What happens if we didn't create the analysis connection?
Hi, whenvever you have parts interacting with each other (and they always do in an assembly, such as contact, fastened, etc), you need to create analysis connection. Without that, they don't see each other ,
@@naderzamani5752 The procedure after Analysis connection as following right? 1) Do analysis connection 2) Do connection properties Thanks for reply
Great tutorial 🫡
Thanks Houman, as you know, these are not rocket science but hopefully will help others.
great explanation👍
Glad you liked it Houman.
Thank you so much for your useful videos. I have been studying CATIA V5 analsis watching your videos. They are giving me big help a lot. I have a one question. I'm wondering why you changed two properties such as Yound Modulus and Density 0.1 respectively. I would really appreciate if you could let me know about my question.
I am glad the yoi found these useful. Note that we are actually creating beam elements (which have axial stiffness) and mass. To make sure that they do not effect the natural frequencies, we make these values very small (reduce Young's modulus and the density)
@@naderzamani5752 Thank you very much for your reply. I understood whar you're saying.
excellent
Many many thanks
Super super, thank you
I am glad you found it useful.
How can I extract forces and moments from the line analysis or seam welding edges to use this data for my weld sizing ? Somehow I cant extract this data via reaction sensors
Please see some of the videos that I have under "local sensors"
Thank you for the good video information.
