You 'll always be my best OpenFOAM tutor, great simplification, strait forward sentences, and as always it's so nice to see you.

Thank you for the tutorial József! Your videos are really helping me a lot to improve my knowledge about CFD. In the near future I'd like to write my master thesis with the help of OpenFoam. Thanks to you it is now made possible! Keep up creating videos like this!

Man I wish all teaching were done the way you teach. Many teaching is done on the assumption that studnets know everything or pick up things fast. I wish I can have you as my mentor I am doing a turbulent combustion and its enjoyable and hard at the same time :) :(

Thank you! Long-time STAR-CCM+ iser and dabled in a few other commercial codes. Your videos are proving the best for finding my way around OpenFOAM now that I have set out on my own and would rather not pay 5-figures yearly for a little user-friendliness...

2022 and Jozsef is still one of my most important heroes. I put him up there with Frodo Baggins.

Very good tutorial and explanation on picking my solver, thanks a lot Joszef!

Your videos are very much helpful for new Openfoam learners :) Great Work ! Jozsef

Thanks! That was VERY useful video! I even have downloaded to PC hard drive) Vedeo really provides the structure of OpenFOAM.

Thank you for the video, I want to ask you a question.
Let say I was able to choose a suitable solver, how can I choose the Linear Solver and Preconditioner in fvSolution for my simulation? More specifically, what Linear solver and Preconditioner should I use when I want to reduce the calculation time but still can get a good results? or can choosing an appropriate linear solver give me a better result when my mesh is not very good?
It would be great if you can suggest some documents for me to read in order to better control my cases.

It is possible to do Moldflow Simulation as CFD or with OpenFoam? Moldflow would consider flow, heat transfer, volume reduction in a form and changing from liquid to solid in several steps.

Hi, is there any tutorial of yours about dsmcFoam?

Hi Jozsef,

I have a rough wall turbulent flow simulation project. I have decided to use pisoFoam because it looks suitable for the simulation.
I'm confused because as what you noticed the icoFoam is for laminar flow but my supervisor just told me that icoFoam is able for the turbulent flow simulation. How exactly is it work?

Cheers,
IC

Hi Jozsef.
I'm still confused even though I understood the descriptions of some solvers. Hope you could help me out on this.

I would like to know, if driftFluxFoam or interDyMFoam are good solvers for a sediment transport through the length of a basin. I would like to simulate how much % particle subsides through the length of the basin and the carried over particles at the end section.

Hope you could help me on this.

Hi Jozsef, is there any tutorial of yours about pimpleFoam?

[treadless_ca]

Could you comment on which compressible flow solvers there are and in what instances to use them?

[diabulusalfa]

Hi József, great video!
I have a question that I hope you can help me solve it, I'm working with fireFoam to create a pyrolysis simulation, the problem is that the heat transfer in the solid and gas phases are important to my analysis, and I think fireFoam does not consider heat transfer, so I am thinking in creating a new solver with this two (fireFoam + heat transfer). Should I edit it in base of the chtMultiRegionFoam, or should I add a different equation for heat transfer, since it is gas instead of liquid? and do I have to add it to my fireFoam.C file? if you have any other comments or suggestions, I will always be happy to hear them ^_^
Thanks.

1:01 What I'm not working at a bank 😂

[samidam]

hey .I am new to openFoam.
when I enter the command 'fluentMeshToFoam elbow.msh ' i get 'Command 'fluentMeshToFoam' not found'
could you help to know why I am getting this?

Hi Joscef, i am planning to simulate a rotating water sprinkler for irrigation, i want to know the effect of water pressure and mass/volume flow rate to the rotational speed of sprinkler. what solver i need to use for this problem.


Thank you.

Hi, I am looking to use the utilities say FFT in one of my solvers. Is there a tutorial where I can learn how to do that? Thanks. :)
