ANSYS 2020 Tutorial: 2-Way FSI of a Pipe Bend

[@abhijitpamarty9195]

He's back! Please keep making more tutorials!

[@drdalyo]

Hahaa yupp!

[@ayonbiswas4186]

Thank you, for this extremely detailed tutorial on Ansys. For a week and a half now, I've been constantly headbutting in various KZbin videos to find at least one that I can follow along in a proper way. This helped me a lot. But some how I only had one data transfer option (fluent one). And the data were mismatching a lot as well. (Stress was higher but the required fos was recommended at a lower point of around 2.4...) I followed exactly how the video mentioned. Guess, I've to do the simulation some more times to make it work. Edit: I forgot to mention that in Mechanical settings, under the contact region tab, there were actually three contact regions in total. The one mentioned in video and two others with cross (multiple) sign on them. I deleted those two regions.

[@ahmadSHAHgordi]

Dear DrDalyO, I cannot thank you enough. Nice, utilized and straightforward tutorial. I appreciate you.

[@prabhjotsingh9362]

nyc explanation sir ,i have never watched any tutorial like this (basically all your videos).Clear voice ,point to point explanation .I want to see more videos from ur side on ansys fluent and thermal

[@drdalyo]

Thanks so much!

[@mustapham6890]

Well Thanking you will not pay you back the effort you placed in the Video. But, really thank you from the bottom of my heart for your brilliant work. You instructed us in details ( right click, press Ctrl etc.. ) and explained every step and what to expect. you provided the drawing and the UDF when no one will blame if you didn't yet you did. Dr. Simply you are just a great Person who works with Conscience. My Sincere appreciation

[@drdalyo]

Glad I could help!

the step by step explanation is very good and the quality of the video too.This video is very helpful and always successful

[@daminisingh6490]

hi, I am getting the error, "Update failed for the Solution component in System Coupling. The coupled update for system Transient Structural threw an exception. Mechanical failed to open the database: Unable to Initialize application event handlers in Mechanical. Either the application crashed or Workbench lost communication with it". what i have to do to handle this error

[@mahabuburrahman1901]

Really, the best video on two way FSI. Thank you.

[@drdalyo]

Thanks! Did you have any issues? Did you obtain the same results?

[@usamaniaz2981]

A wonderful demonstration of two-way coupling, highly appreciated!! keep it up.

[@drdalyo]

Thx!

[@Chris32351]

Really straightforward tutorial, many thanks!

[@lidiyabitew9071]

Nice tutorial. Thank you for your guidance. I followed every step but when ever I try to edit the setup for system coupling the workbench closes. Can you help me with this problem? Thank you

[@naviddavanikabir]

very glad to see you again. btw, why don't you upload in 1080p?

[@drdalyo]

Dont have a FHD screen

[@syedmurtazajaffar8833]

Amazing and very well presented. Thanks a lot Dr. DalyO. God bless.

[@Ujwaladanole199]

Wow you are really back more cfd video

[@drdalyo]

Next might be more mechanical less cfd

[@augustowanderlind7963]

I appreciate your videos, they're very help! Congratulations for your return! keep going

[@drdalyo]

Thankss!

[@SoulfullSpace]

Closing SEA in bucket. Thanks man

[@canguler2265]

it's been quite a long time, dr.

[@jimmyloluolajide7777]

You’re the best out there. Please, I’m still struggling with my impedance tube simulation in Ansys (acoustics). Is there any way you could be of assistance? I’ve been on this for 11 months and running out of time. I have some documents I can share if you’re interested. Thanks

[@EddickC2D]

Thumbs up Dr, one of the most valuable channels! Keep it up!

[@drdalyo]

Thanks!

[@rostamr4096]

I have being bing watching your tutorials...can you do one with a factor of safety?

[@drdalyo]

You can check out my cast iron tutorial (kzbin.info/www/bejne/mn2zkmaKhLxgaJI) I believe I talk about the factor of safety tool.

[@SaadKhan-bt4st]

Amazing Video, really learned soo much and it helped me out with my project. Now my next goal is to create Edge on edge impact (ceramic damage).

[@drdalyo]

Glad it was helpful!

[@atheerkhalaf6987]

that was really clear and helpful, thank you & hope you make more videos

[@asifraj321]

An amazing tutorial clears almost all steps in a single video. Why do you not use remeshing? Requesting you to make at least one more video on blood flow through arteries by using 2-way FSI.

[@dressingkrishna343]

Very beautiful presenatation

[@surajpatil2384]

Too good!!,Please do more tutorials on UDF.

[@ryanlucht6625]

It would be awesome if you did a video on udfs

[@drdalyo]

yeah it would be a whole video for itself

[@tasbeehaaalam8341]

I love watching your videos, pls make more videos 😊

[@drdalyo]

Thank you! I will try

[@anshulsuri5619]

A great tutorial setting basics for FSI, really helped me

[@drdalyo]

Glad!

[@MechTechSimulations]

Awesome Tutorial

[@drdalyo]

Thanks thanks

[@mertcakmak134]

Hey thanks for that perfect video. I wonder how to solve if the fluid inlet and outlet are variable. Like a situation that have both holes are inlet also outlet under constant volume.

[@Medzforya]

Life saver🙏🏾

[@jonh7944]

EXCELLENT tutorial. Thank you very much!

[@drdalyo]

You are welcome!

[@mathanagarathi]

Thanks for the great tutorial DrDalyO. I followed same concept of FSI on cantilever beam under induced flow. Can i know how to transfer the surface pressure created by fluent flow to transient (beam) to obtain the harmonic responses. -Ansys 2021-R2 -System coupling 2-way

[@mityajussrssr4]

Such an informative video. Keep up the good work.

[@drdalyo]

Thank you!

[@echarkaouisomman8239]

Thank you for this amazing tutorial 😊😊

[@amirali-sp4rc]

many thanks for this awesome tutorial. can please tell me how to open my results in mechanical. FYI: I run my simulation on cluster. I really dont know how to open them in ANSYS mechanical

[@wkuntjoro6130]

Excellent explanation. Thank you.

[@xavicastello1]

Excellent tutorial!!!

wonderful, useful, detailed - it is a pleasure to learn from this.

[@belaidashur]

Great .. Just great ...

[@jeevanp5239]

Please do video on quality check.

[@LOMADAKARUNAKARREDDYRS]

Good informative video

[@energyengineer5266]

Please make a video on Swirl Flow in a beaker having water in the beaker with a magnetic stirrer. First without any hindrance in the beaker, then with hindrances in the beaker (like semi-circular, triangular, and rectangular hindrance). Thanks.

[@vikassingh4577]

Nice explanation..can you please tell me where you have used the material created in engineering materials (water)? As your both of the components in transient structural are assigned to structural steel.

[@eshrakjamil3366]

Can I do 2 way fsi in student version

[@farzaddizaji7002]

Very nice tutorials!!!

[@annenoniem]

Hii, we are recreating this for practice. However we did not get 2 data transfers and we followed every step the same. Do you have an idea what might have gone wrong?

[@thansiyapa4721]

i too have error.did u resolve it?

[@rostamr4096]

Great tutorials..Thank you.

[@drdalyo]

Thxx!

[@nicolamenga8943]

Hello. Thank you for the video. I have a question. Why the reference values should not be changed in this case? For example, in the simulation of the airflow around a wing section the values in Reference Values must be changed (for example Area = chord length: density = air density at the simulated altitude; velocity = air velocity at far field, pressure = air pressure at the simulated altitude). Why in the example of your video not? Thank you.

[@brianyeh2695]

Extremely helpful!!

[@InanSakar]

Hey can you do a suspension bridge tutorial

[@obadaalkhamis3680]

Hello thank you very much for your huge efforts Qu : could I use these steps for problem (2 way fsi between artery wall and blood flow

[@ata992]

Hi Sir, can you please make a video on how to do a pull-out test (modelling the bond)? I can't find a good tutorial. Please help cos I find your videos to the point and clear!

[@kieseopkang3772]

very useful tutorial. Thanks

[@silverX362]

Does the flow simulation accounts the deformation of the pipe for each step? I am on my dissertation assignment in MEnG, and this would play crucial role.

[@sumantalaha5187]

i am facing a problem in the coupling update "(DP 0) The Setup component in System Coupling requires user input before it can be updated. Edit the System Coupling Setup cell, then right-click on any ? in the Outline tree, and select "Display Validation Failure" for more details." Please help how to resolve this issue.

[@letscomment11]

Wow, u are back😀😀

[@drdalyo]

I am!

[@유현동-d2k]

thank you for your video! and i have a question. Is it possible to have 2D FSI using Ansysworkbench?

[@drdalyo]

Yes it is!

[@유현동-d2k]

@@drdalyo I heard one way to do it in 3D which has no nomal force and some people told it 2.5D. is it possible?

[@MrHaoca]

It's very usefull. Thank you

[@drdalyo]

Welcome!

[@syiratee3428]

Thankyou! keep it up.

[@rjw678]

Great! Is it necessary to solid first and then fluid?

[@lol1kzizka]

Great tutorial, very helpfull!!! Thank you for the upload:)

[@drdalyo]

You're very welcome!

[@cve0917]

Hello bro.. can you upload the video about the processing of steel concrete composite column?

[@nikhilsrivastava8819]

Hello sir, i am working on 2 way fsi, this video is so much helpful, but i am facing an error in it. Can you help for it?

[@drdalyo]

Please post the error message

[@gustavosilva-o2z]

HI , thanks for your video, I have a question , as soon i undertand transient analys can be used when there is changes in velocity and/or pressure flow changes in a specific period of time, (please let me know if there is a lack of information) . I am not shure if this time is short or long? and what happen if i want to make an analisys at any time? should i use transient analys too in ansys or other toolbox, thank you in advance

[@3abbara1]

Thank you for this video, I did run into an issue, however. when I created the hex dominant method and updated the mesh i kept on getting error message. 'Mesher failed to generate hex dominant mesh for one or more bodies. try using a different mesh method.' would appreciate any clarification.

[@fablzz335]

Hi there I have a question. Can you make tutorial for ACP PrePost for example for sphere? It`s can help me so much. Thank u for your videos.

[@shuvekshasapkota5574]

Would you make video for a circular microtube or rectangular?

[@drdalyo]

Not sure but I can make a note of it!

[@austineadah2843]

Is there a way to validate these computations by hand or write some simple codes from scratch on this?

[@sankark7956]

Can you tell me on what basis dynamic zone and its settings has to be chosen?

[@muhammadafifaniromadhan8562]

Awesome

[@SK-tg1vw]

Need some help on this with extra geometry, will you do it?

[@Jiam2905]

can you please help me in selecting a topic for my final year project? i am an engineering mechanical student...wanted to learn ansys from your videos & do a project using it...pls replt

[@ES-or6kw]

Hi, I am wondering why 4 cells boundary layer was enough, isn't it supposed to be 10+?

[@drdalyo]

It depends, but yes 10 would be more accurate.

[@lorisk964]

when we see the velocity and the hydraulic diameter we can say that we have a big Reynolds number so why the flow appears laminar ?

[@destineos8038]

20:10 why I haven’t Fluid Flow and Fluid Solid interface links ? It seems like the Setup for Transient Structural is not complete 🤔

[@jimmyloluolajide7777]

Please, I need your assistance on how to plot any result along the length of a circular duct in the z-axis.

you are doing wonderful tutorial , i got lots of benefits from it ,,, COULD YOU GUIDE ME HOW TO DO SAME BAT AN ARTERY WITH BLOOD FLOW , THE WALL MUST BE ELASTIC

[@SathishKumar-gi6os]

Bro pls design involex turbine pls

[@emreerdogan4360]

Are you using ANSYS as a licensed software?

[@aminubukar308]

Hello, Please I tried running the same fsi simulation on a straight pipe. But there is a larger deformation at the beginning of the simulation. I used your UDF on the same pipe and it still have that large deformation at the beginning of the simulation. Please how do I rectify this problem? Thank you

[@drdalyo]

Maybe try without the UDF? also check my description info, I listed some troubleshooting tips. You can also try and change the size of the mesh (larger or finer)

[@houssambensalah7488]

Please do u have an idea about overset mesh ?

[@drdalyo]

I may do a video on it in the future but for now please check other videos!

[@qwertyuiopp618]

23:00 fluent results

[@techhunt4922]

What if i need to do a Modal Analysis with it?

[@gustavosilva-o2z]

Second question sr, why you desactivate the water component, if we need to analize de fsi? in minute 7:32, does not affect the answer, I DO NOT have clear why please

[@surajshembekar5583]

hello sir, this video is so helpful , thanks for making this video. I have tried the same as you explained in the video tutorial but on the different geometry as per my requirement, different material, and interpreting different UDF as a inlet velocity BC. different time step and end time. but when i run the system coupling it shows the error as: "Update failed for the solution component in system coupling. the coupled update for system transient structural threw an exception. error updating cell solution in system transient structural." please help me

[@JamesZhang-bj6kk]

Hi! I have faced the same problem. Did you find a solution? THX!

[@haikalsheeran6556]

helo sir, just want to ask a question. during system coupling in my project, it does tells me that "system coupling run completed successfully", but in the chart monitor, it only shows the green line. there are no red lines appeared. So, does the coupling is really successful or is there some problems?? By the way, i am coupling between fluent and the steady state thermal & static structural (thermal stress)

[@nasrinsam5689]

HELP PLEASE! I accidently deleted the "fluid materials" in engineering data library. How I can recover it

[@drdalyo]

Hi did you resolve this issue?
