wow, such a great explanation. I am submitting a simulation report tomorrow and this video helped me to better understand the concept and to better document all the results. Thanks a lot. May god bless u :)

The best video on basics. Thanks!!!

More than helpful, thank you!

Yup, crispy informative video

Great video. Thank you so much. 🥰

Hello Ansys Learning Great video Thanks, I am not sure but I think there is minor a mistake at 3.37 where {D} is the vector describing the direction instead the unit displacement spectrum isnt it? Thats what it's says on the docs. Anyway thanks for the video

Liked it. Explained nicely

Mam, can you please make video for performing modal analysis of structures under Water. or can you please tell me how to consider the hydrodynamic added mass on the structure while performing modal analysis in Ansys. Thanking you in advanced :)

Good Video. But my basic doubt is, if there are no external load on the structure, why structure should generate modes and frequencies? It is like, If I fix a sheet with 2 bolts, that sheet will not vibrate until and unless If we excite. Please clarify. This might be basic question.

Thank you for the explanation it is very helpful

Thankyou for this explanation. What is the method to troubleshoot the analysis from solution output or make sure the total deformations are correct? What changes can be made if the deformations are higher than expected.

thank you Sir but can you tell how can i find a longitudinal natural frequency axial vibration please

Mam can you please update on how to export mode shape from ansys workbench

Please also teach how to do modal Analysis of machine submerged in water. For example, pump impeller or turbine runner of francis turbine are working with water, so how do i do modal analysis in water for this mentioned case?

Thanks a lot for your kind information…. Can you provide the information about motor frame analysis for frequency basis

In a modal analysis using a structural-acoustic coupling ("eg. a beam that vibrates in an acoustic medium"), how can the operator know if the mode is coupled or no using the participation factor? Any thoughts? Thank you.

Is it possible to extract the mode shapes (deformation results of each natural frequency) into 1 excel file ?

where I can find this video in Ansys Innovation courses???

Modal analysis is valid for linear analysis but due to damage in structure if non-linearity of structure happens then how the modal analysis is still valid on this damaged structure ??

Can you please update vedio on how to perform MAC ( modal assurance criterion) using ansys

thanks!

how to solve this problem"Fracture commands are not sent to the solver for the modal analysis. If needed, please use the Commands object to issue the necessary commands. "

deformation plotting against modes shapes are getting 245 mm like does it even matter ? second should i opt large deformation ON ?

Wait a second What is the difference between participat factor and effective mass? By definition it seemed same to me!

Hello, why deformation in modal analysis so big compared to harmonic analysis?

Why we take 6 number of mode for analysis?

Grt explain

how could I extract strain energy plot for designated mode based upon modal analysis ?

How can I use dynamic analysis in APDL for steel frame?

how to get the sum of eff. mass
