I have a several questions: 1. What about the multiples of the exciting frequency? 2. Is every freuqency here relevant for the rotation of the fan? I mean there are modal frequencies for bending and other modal frequencies for torsion. I think the relevant eigenfrequencies here that might cause a resonance case for the rotation of my fan the torsional eigenfrequencies.
Thank you so much Karthik for your feedback, this will help me improve the quality of my future tutorial videos. Please share this video with your friend's or those who are interested in learning ansys, if any one is interested in online training from me please contact engineeringtutorsdesk@gmail.com
I create a model and when further go to in geometry choose faces there is an error occurring frequently. Warning: Face pair selection tolerance.suggest 6.25-006m.I don't know much more about ansys, so what am I suppose to do??
Sir the video is really very much informative and you have explained it very well. can you please tell me how to give fixed support for a solid rod on its curved surface for specific area.
Sree Nivas, we use mid surface to represent the constant thick walled parts, and to capture the bending behaviour more accurately. In ansys, as soon as you extract mid surface for any constant thickness walled parts, it automatically records the thickness, this thickness will be show when you do the surface meshing. you can write me on below mail ID, and visit my website for more videos.

What is the significance of total deformation??? You've got almost 20cm as deformation value at 3:54 sec, does it mean that the red colour zone is having maximum deformation of 20 cm or the entire propeller is having 20cm deformation
Thanks for the video. I have one question about Total deformation output which comes from mode shape result. How can i interpret total deformation values? Are these the real values? If not, how can i get the real results when it gets resonate.
hello , nice video & your explanation is very good , good effort it will be easy for beginners...I have one request plz upload any assembly unit modal analysis .
1. sir why did u extract the mid plane for analysis ? 2. sir it would be really helpful if u can make a tutorial on efficient meshing ? and by the way great tutorials sir
thank you for your video, I would like to ask you about How can I do the natural frequency model for a non. Reflective boundary conditions for the soil surround the tunnel, so I can measure the natural frequency (free-free vibration analysis) of the model Without duplicating the measurements from the reflection of the wave, or ANSYS mechanical will understand by default that it is a non reflective boundary, so the wave will not reflect and it will go for infinity since the soil model is plan strain model? Please advise. Please note that I made a search and found that only ANSYS fluid can have this option for the user to choose the boundary conditions ( reflective OR nonreflective boundary). appreciate you help and support and I will wait for your respond. Thank you Khalid l dous
HelloIm glad I can find these kind of videos, thank you so much. I would like you to present some references as I need to do a modal analysis for my ansys course and I cannot put as a reference a youtube video :S I don't know where to find that the natural frequency cannot be equal to the value in rev per second.
@@ANSYS-India thank you for the quick reply sir. I actually want to do a free free modal analysis (Ships etc). For example a Cube immersed in water or floating.

@@ANSYS-India sir many thanks for taking time and searching information for me. I actually did come across this thesis a week ago. but it didn't have the solution for my problem.
+Chukwuka Nwobi Greetings!! Mid surface was used to use the shell elements, because the shell element capture the bending behavior more precisely compared to the solid elements like Hex and Tet
Greetings! ! Raj the element selected will be automatic, because in workbench before you start the analysis, you choose the analysis type like static, modal, thermal and so on, due to this the relevant elements will be used by default for the mesh generation. But order of the element can be changed manually. If you are interested in knowing which elements are used then please see the output window after the solution is completed.
I had to watch at 1.5x speed to feel normal. lol
Your comment just saved my life sir...
It felt like an aggressive advertisement..
Same
same here bro but the video is so good specially the elaboration of result part
2X here
Thank you for your tutorial 😌😌
Thank you very much for this nice tutorial. It's good that you speak while using the software, it enhances the learning experience.
Thanks again!
this is outstanding, best explanation
Great tutorial. Made it all so clear.
wow!! absolutely amazing explanation. Great work. please continue to make many more such videos about ansys.
Thank you for liking my work. I will continue making new videos.
thank you for this video it is very clearly explained each and every point and every one is able to follow this
Karthika, good to know that you liked my work, pls visit my website for more tutorial, sites.google.com/site/feaengineeringdesign/
great explanation!
best tutorial ever, Thank you Very much

Hello Sir.If I want to get the results at 60Hz, where to enter this frequency
Very good explanation. Why you use mid surface?whats the rationale behind using mid surface concept?
Sree Nivas, we use mid surface to represent the constant thick walled parts, and to capture the bending behaviour more accurately. In ansys, as soon as you extract mid surface for any constant thickness walled parts, it automatically records the thickness, this thickness will be show when you do the surface meshing.

good explanation,
ok it is in static condition, but how can i find the frequencies at required rpm's (N1, N2,....) to draw the campbell diagram...
THANKS!!
sir how did you model the rotor fan? in catia creo or some other workbench? also if possible put up a vedio for the modellign part as well.
HelloIm glad I can find these kind of videos, thank you so much.

Vedio is very good . Can you tell us how to find the amplitude of vibration
how we can do the modal analysis of a multi leaf spring in ansys workbench ?
what are the boundry conditions for it?
Is mandatory to fix the body to find out natural frequency in free-free analysis ?
an amazing work.but this tone......em. I have to speed up this video.lol
Sir do you have any idea how to do modal analysis of structure under water in Ansys.
as there we need to consider the Hydrodynamic added mass.
One of the approach can be, you can do pre stress modal analysis. Create static structure analysis with pressure load, then do a modal analysis
@@ANSYS-India thank you for the quick reply sir. I actually want to do a free free modal analysis (Ships etc). For example a Cube immersed in water or floating.

Too slow and too much good info. thanks!
Why did you use mid surface? doesn't it affect the thickness of the rotor and hence the vibration response?
+Chukwuka Nwobi Greetings!!
Mid surface was used to use the shell elements, because the shell element capture the bending behavior more precisely compared to the solid elements like Hex and Tet
is harmonic vibration and axial vibration of a rotating shaft possible in ansys?
+Biswa Swain Yes
you have not specified about element type, will it pick automatic or do we need to specify.please clear this

can we use this for a 3d beam?
+chaitanya naidu Yes
Forexample I want to check how strong (amplitude) the frequency is at 167 Hz. Where can I found this information?
Roman, you need to conduct harmonic analysis to get the amplitude.
is it possible to do it under Ansys?
Yes
how to find whether it is bending mode or torsion mode? pls anyone can help me?
Allocious Britto Allocious, all modes you can be found in the analysis, need to enter the number of modes before the beginning of the solution.
how to decide max number of modes
how did you do for desing?
+diego manuel pacheco molina Sorry I did not get you
can u upload this working file sir
Please share CAD file...
