Lid Driven Cavity Simulation in ANSYS Fluent | 01 | Implementing the CFD Basics

[@TanmayAgrawal7]

This was all about software. Wondering how you can write the code for the same problem? Check out the tutorials here: kzbin.info/www/bejne/hIiqiqeajqirabc

[@abhishekskumar5586]

Displaying the mouse pointer would be helpful as that will let us now where and what you are selecting. Thank you

[@chris0062]

REALLY helpful vid! by far the best tutorial i've found for beginners on ansys!

[@omerbinhussain4636]

waiting for the next video since 15 days.. These videos are very helpful for beginners and can be an excellent teacher if you continue your struggle continuously.. Thumbs up for you... Thank you

[@omerbinhussain4636]

I liked it.. thank you my dear.

[@upmasingh8616]

Short and complete........superb....I really like it ......thanks🙏

[@AnNguyen-bf9iw]

Thanks for your tutorials. Can I ask about why the continuity residual can't converge

[@TanmayAgrawal7]

It is also converging if you see the white line. It is not as small as the other residuals.

[@saidferdjallah6680]

I remember doing this with implicit finite difference scheme with fortran program

[@k-lyuniverse4200]

Great video! I have a question, I'm working on the same problem but with imposed tempratures on the moving wall and on the bottom one, and i am trying to visualise the temprature contours to show the effect of convection for different Richardson number. Can you tell me the exact parameters that i should change in Fluent solver in order to study this case? Thanks you in advance.

[@TanmayAgrawal7]

When it was an isothermal case, we change the top wall boundary velocity (lid velocity) in order to change the Reynolds number. Similarly, I believe you can have different combination of parameters (delta T and U) to have diff. Richardson numbers.

[@AeternWarrior25]

Very good tutorial, keep them coming!

[@MechTechSimulations]

Great tutorial bro..

[@TanmayAgrawal7]

Thanks!

[@nasreenganie877]

great video!! do you perhaps know how to do it for buoyancy driven flow , also dependant on reynolds number?

[@TanmayAgrawal7]

In my opinion, you will need to add a body force term in the equations.

[@Zander101084]

Trying to follow you on ANSYS was harder than learning CFD

[@TanmayAgrawal7]

I'm glad I could make CFD learning easier :) Thanks for the comment though, I will improve in the upcoming videos.

[@anaslahrichi]

Thank you sir

[@abdulganiyusalaudeen7640]

Good day. Thanks alot .I used this method to validate a journal (mixed convection in a lid driven cavity) by R iwatsu et al. The contours look alike but my nusselt number were off .. could you the vid for me or share me some tips thanks in advance

[@abhishekattal7913]

Great job man

[@sumitsrivastava8872]

In geometry how can we decide whether to add surface body as solid or liquid ?

[@TanmayAgrawal7]

If it's supposed to be a fluid domain, call it fluid.

[@amulyadevalaraju357]

could you please make a video explaining how to analyse the double driven cavity flow in rectangular slender cavities with parallel walls moving in MATLAB, and provide the code please

[@TanmayAgrawal7]

Towards the end of MATLAB series, I'll go through the lid driven cavity problem. Maybe not exactly the one you mentioned, but the idea would remain the same.

[@kirpahirom7209]

Hello bro i am new to CFD. Please suggest how to get a good foundation about this subject. Thanks FYI i have learned basic geometry drawing and meshing too but still feels weak about its working and sorts specially those options in the setup.

[@TanmayAgrawal7]

If you're after concepts, please start with a book. Anderson's book is an extremely great start. For software, knowlege comes handy otherwise you'd feel like pressing buttons and getting all sort of results. Meshing in itself is a huge segment and many things affect it. There are many online courses about CFD. Please refer to NPTEL website.

[@kirpahirom7209]

@@TanmayAgrawal7 Will look into that. Thank q for your time

[@salmanbeg276]

Sir i request you to please make one video tutorial for flow in rectangular open channel of length 5 metres and width 15 cm with a small rectangular cavity attached below the bed of open channel. Width of cavity should be equal to width of channel and length of cavity can be taken as 30 cm using VOF model. I shall be very thankful.

[@TanmayAgrawal7]

Hi, please refer to my latest upload.

[@ra.swarnava484]

i want to make a bubble flow column, can you suggest me something how can I do that?

[@TanmayAgrawal7]

I guess you should be using VOF multiphase model for such problems.

[@siddhikesharwani3419]

I am very new to this CFD and using Ansys 19.1. These tutorials are beneficial, but could somebody guide me to the resources (tutorial) for a basic understanding of tools/functions for open channel flow. It would be very helpful.

[@TanmayAgrawal7]

For a basic understanding of theoretical aspects, you can refer to the Fluid Mechanics book of Yunus Cengel.

With the recent iris xe graphics with the 11th gen i5 16gb ram compatible and sufficient with ansys for medium 3d simulations?

How many cores are there? RAM should be fine for not very intensive 3D simulations

@@TanmayAgrawal7 it had 4 cores and 8 threads. ..and integrated iris xe graphics. Actually I'll be working on LBM simulations. ...so how are these specs from that point of view

Does ansys has lbm? I don't think so...

[@imwaz3644]

@@TanmayAgrawal7 Actually I'm the beginner into it so I don't have much clarity...It's what my guide has told me.....can you please tell that which tool is exactly used for LBM simulation? And it's system requirements for low to medium 3D simulation?

[@TanmayAgrawal7]

You'll need, most likely, a coding based platform. LBM can work on parallel system, so having an Nvidia graphic card or a system with more number of cores would always be useful.

My screen becomes black in 3d viewer in results section ..what should I do ??plzz anyone help 🙏

[@faridkasrakeya]

you are very fast, cannot follow you. I cannot see the mouse pointer

[@venukr937]

In ANSYS ,you have taken steady state ,but in nxt coding video you have taken it unsteady problem ,Why? reply appreciable

[@TanmayAgrawal7]

Sorry for the late reply. The reason why I chose unsteady in coding is to demonstrate iterations in time domain. Ultimately, if there are no perturbations for an unsteady state problem, it yields and becomes a steady state solution.

[@vidyadharnaik3914]

can i get the theory of the total process
