Nicely presented about the importance of modal analysis. To be more specific this method is fixed-free condition to identify the frequency responses based on the applied vibration rage. Typically the ESE results in positive values and we can identify the "potential failure areas" before applying the structural BCs and LCs. When ESE result in negative values then it means your BC is inaccurately defined. I'm sure you already know but there is another method called free-free condition, this is exactly same as fixed-free, only difference is removal of BCs. I used this method to check the element quality and potential numerical errors within the model. You can expect the epsilon values to be nearly 0 as close as possible as there is no fixed BC to respond. The Industrial standard is typically less than 0.001 when meshed accurately. When it is greater then re-meshing needs to be performed around the region. Due to the time restriction, many analysts skip this stage and directly jump into the LCs for quick analysis results. It is okay when you're confident in your modeling techniques. But as we all experience numerical errors happen often and random, and we might save more time in the end by catching these potential issues in the early stages. Always remember.. Garbage in garbage out.

Nice Presentation. Kudos to the presenter. Simple and covered all neccesary information.

thanks...you r great, very helpful for me

Great content to get a quick overview

you are doing a great job! keep it up bro, presentation was clear and understandable. Thank You!

These videos are great! Thanks for sharing!

Excellent explanation

Really appreciate your work brother!!

thank you for a job and good explanation

Very Nicely explained...Thanks

great videos, thank you for uploading this!

Thanks a million Brother :)

nice explanation bro keep on moving all the best

Nice Video Sir, It will be help us to modal analysis setup

superb bhai, well done

Great vídeo

Hi, thanks for the video. Btw, Hypermesh in my PC doesn't have the EIGRL card.. Do you have any idea with this issue? Solver interface is set to Optistrut, correctly. To be more specific, below is the list apppears on the Load collector Card Image dropdown window. '..., DTI, FATDEF, ...' As above, there is no EIGRL card on the list..

Pretty Good explanation......upload more analysis like dynamic and pseudosound etc

Thank you so much

Preety good work bro... Do also include some really explain good things like modal effective mass and modal fraction for better information.

Great work... Needs tutorial on direct and modal frf

Very useful

Love your videos! ANy plans on doing videos on Hyperworks 2020 since it is a newer interface?

Hi, You have used first order tetra elements for the analysis. But usually we use second order tetras right? Because first order will be inaccurate results. May I know the reason.

Great effort. I have a question that which meshing type is more preferred in this case, a Tetra Meshing or a Hexa Meshing? Please also specify the reason. Waiting for your response..........

I'm planning to topology optimisation on a component. I already know that static structural analysis is integral for this process. If I want to do modal analysis, can I incorporate it into the same process, and will it impact the topology optimisation at all? Any help on this would be much appreciated. Thank you.

Thanks, Sir Nice and clear explanation, when I performed this analysis it showing me this error "Incorrect data in field # 3. Field 'PID' of CTETRA bulk data." What should I do sir?

Hi, and thank you for the video. Can you show how to perform modal analysis on a model with non-linearities (contacts, non linear elements, etc.)? Thank you in advance.

What is significance of setting frequency in modal analysis?

not able to find eigrl card against the card name..please help

Hi sir, great video and very clear explanation. How could i find the oscillating mass and the oscillating period for each vibrating mode? Thank you

Hi, thank you for this tutorial, can we do modal analysis including rotor dynamic analysis for Rotor ?

Hi sir, i cannot find eigrl card image from drop down menu can you tell me how to add it

Sir,how can we show the deformed and undeformed shape simultaneously in hyperview?

Sir, why do you choose 10 for the number of modes (ND)?

How did u decide number of modes ? and what did u mean by intire spectrum

How to provide contacts to bearing in Hyperworks

Is the normal mode analysis and modal analysis are same ?

Sir make a video of gear analysis

Awesome 😊

how can input the SolidWorks 3D Design this Software bro ?

Hi pls tell me how to remove error 1485 and 1000 when we run file.

Please provide cad file also.

1501 fatal error occurred

Oh god, I like Indians
