Linear Buckling Analysis using Hypermesh [Optistruct Tutorial]

[@m.ssharma535]

Excellent summary of Sol 105 in MSC-Nastran / buckling analysis using OptiStruct.

[@omerfaruktayfur7031]

quite useful tutorial about linear buckling. Your interpretation is very clear, thanks dude

[@Aeroswap]

Thanks! Glad it was helpful :)

[@s.s.divakar7911]

Hats off for explaining it clearly and I am your regular viewer, waiting for your next move

[@Aeroswap]

Thanks! Glad it was helpful :)

Great work, really its helpful for us to improvise in our field. keep posting similar videos.

Thanks Raj! Make sure to subscribe to stay updated about the latest videos posted on this channel :)

@Aeroswap Thanks a Ton! Really appreciate it. But how about the case with nonlinear buckling? Do we have any insights on that?

[@allunknowns2110]

Hello sir , can you shere some info about fatigue analysis on steering knuckel of vehicle , please

[@Aeroswap]

Hello, I am working on a fatigue analysis tutorial. It will be out soon!

[@allunknowns2110]

@@Aeroswap i am working on a project i needed it on urgent basis, can suggest something else video or research paper for now .. It will helpful.. Thanks for reply.

[@Aeroswap]

I have not seen any good videos about fatigue analysis using Optistruct on KZbin. I would suggest you to directly refer the Optistruct user manual for your project work!

[@emmanuelvassilakis5630]

Nice Swapnil. Now go for the NL buckling analysis!

[@Aeroswap]

Working on it 👍🏻

There was nothing in cad model

Thank you!

Hi! Can you please post a video tutorial on how to model RC slab and beam using Hypermesh for beginners. I have not found any videos about modelling structures using Hypermesh on the internet.

[@Aeroswap]

Thanks for the suggestion. I will consider working on this topic soon.

[@MohitKumar-ro5ew]

Dear sir, can you help me in solving inertia relief on a spring.

[@Aeroswap]

Sure. I have not posted a video about inertia relief analysis yet, but the setup process is similar to a modal analysis. 'SUPPORT' boundary condition has to be applied instead of SPC.

[@user-ir3oy1nk8t]

sir I use hypermesh student version, I am not able to 'drag and select' anything, is there any software setting?, please help.

[@Aeroswap]

Press down SHIFT key and then drag. This is the way it works.

[@user-ir3oy1nk8t]

@@Aeroswap it worked, thank you 😀

[@kradonrace]

I don't have "EIGRL" in the card image list? Is it because I've selected optistruct at the beginning?

[@AbhishekSharma-hh6kj]

Thank you bro👍 I have a query that how we decide the element size. Whats are the criteria behind choosing a specific element side?

[@Aeroswap]

There is a concept called 'mesh convergence'. I will not be able to explain it here in one comment. Please search about the same if you can. I also plan on posting a separate video about this topic soon. Until then, you can always contact me via email regarding any doubts or suggestions. My email id is provided in the 'About' section of this channel.

@@Aeroswap Ok thanks alot. Please also make a video on Linear Transient Heat Transfer Analysis

[@Aeroswap]

Thanks for the suggestion. I will try to work on this soon!

[@AbhishekSharma-hh6kj]

[@kenkim2687]

Great work Swapnil. When I first learned buckling analysis long time ago I was confused about the eigen value and what it contributes to determine the critical load. Nice job using 1 to explain the critical load for the beginners. Is ur next buckling analysis going to be non-linear? Haha

[@Aeroswap]

Thanks Ken! Yes, absolutely. Emmanuel has done a great job by providing me with a nonlinear buckling case. We were working on the same for the last few days. It is almost ready and will be uploaded soon :)

[@SivaKumar-zy8pr]

Hi , can we do all the preprocessing in Hypermesh and solve in Ansys. We do not have optistruct solver license ??

[@Aeroswap]

Yes definitely, you can do preprocessing for numerous solvers in Hypermesh. Ansys is one of them!

[@SivaKumar-zy8pr]

Your way of explaination is very clear and thorough. I suggest you expand by making technical sessions on FEA also. It would be very helpful for us

[@Aeroswap]

Thank you!

[@swanandpachpore2714]

good directives to perform linear bucking analysis. i have some doubts realted to similar geometry. by what way i can contact you? your videos are really informative

How to give rotational velocity in optistruct

[@Aeroswap]

What are you trying to simulate? Optistruct is mostly used for static analysis and optimization so velocity is not a commonly used boundary condition.

[@Foodie_Cooking_Loverz]

@@Aeroswap I want to to simulate drum mounted on 4 pulleys with drum rotation...so which solver should I use?

[@Aeroswap]

Radioss

[@Foodie_Cooking_Loverz]

@@Aeroswap thanks

[@Foodie_Cooking_Loverz]

@@Aeroswap but is it possible in radioss to do static dynamic analysis

[@shoebqureshi7359]

on what basis we assign thickness value ? (In property )

[@onkarjalkotkar5647]

Sir, have you already made contact with those two model of Hopper & Frame ?

[@Aeroswap]

Hello Onkar, The two components are geometrically connected. I designed the model that way to avoid complexities. You do not need to create any contacts or joints. Just organize the surfaces (if needed) and you will be good to start with the setup as shown in the video 👍🏻
