Thank you Alexandre, it took so much of my time.

@alexandrefernandes6286 Dear Alexandre, I am glad you found it useful.

quick google search says press shift

Sorry, I do not know the answer to your question.

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.

Dear Shanny, I am glad that you found it helpful.

Hello Aleksander, this is a third year summer course for mechanical engineering students at the University of Windsor in Canada.

Dear Armit, my guesss is that you have to, you have to write a "Macro".

I am glad you found it useful.

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".

Dear MRY, I will discuss your suggestion with "Aghaye Soroush" and we will put something together for this topic.

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.

Ok, I will post it as an announcement on Brightspace. If I forget, please remind me in class.

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

I am glad that you find these useful. Unfortunately, things are not well documented.

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.

Thank you, I am glad you found it useful.

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

Thanks

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

Dear "user-tz9fl1yv7r", I am not a CAD person and therefore cannot make meaningful suggestion. Good luck in your new job.

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 ?

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.

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

Thanks dear Amin.

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

Thanks Houman, as you know, these are not rocket science but hopefully will help others.

Glad you liked it Houman.

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.

Many many thanks

I am glad you found it useful.

Please see some of the videos that I have under "local sensors"
