do you have python scripte for dns or les of turbulent flow?

great. my case has problem of " no heat transfer between fluid and solid region" , do you have some ideas about it?

Can I use different number of partitions at the top and bottom of a line using Transfinite? Because I need fine mesh at the top sub-surface and coarse mesh at the bottom sub-surface.

Very helpful video! But how can i create blockmeshdict file in system directory? Is that not necessary to run the simulation?

Thank you for the video. Im having trouble using .msh.h5 file(fluent mesh) file to openfoam, How do i convert .msh.h5 to .msh? any help would be appericated

Thank you for your tutorial. However, I got divergent result at time 60 without changing any parameter when I run your case download from git. Then, I changed relaxation facrors U 0.95 -> 0.9 and "(k|omega|epsilon)" 0.95 -> 0.8. It finished but provided wrong result. "U" is zero on impeller and very small value on "top", which are different from your results. I only changed relaxation facrors. I used OpenFOAM(org) version 11.

Thank you!

Great video, the most detailed I've found on GmshToOpenFoam!

Dear asma, thanks for this great video. However, when you added the z and turned the case into a 3D are you referencing or replicating any experimental work?

Hi, anyone tried compressible fluids meaning including density in the flow rate equation? *thanks, Asmaa*

Hi Why did you delete the turbulence properties model

How long does it take to run the file directly to get results?

thank you so much for the tutorial, it helped me a lot!!!

How can we run own case setups on open foam?kindly tell about this.

Hi, Thank you so much for your useful video. I have a question. I would appreciate it if you could help me. I have some particles which move in the water, I want to see their movement by streamlines. Is this possible? Thank you so much

Thanks asma your videos are amazing it helps a lot.

Thankyou for the video. How can we address the value of alpha when calculating flowrate in interfoam?

Hello nive work. I am trying to simulate a very similar case, but with the difference that i need water as fluid and that the external walls also can describe a material with temperature. I mean an external wall with high temperature, the internal sphere with low temperature and a liuquid flowing fluid. Is it possible ? Regards

This was helpful, thank you!

thak you good

Nice explanation ❤

Salut, merci pour votre effort je veux savoir comment je peux récupérer le module paraview.simple ?

On vertices 0, you added 0.5 on z axis? can you please tell me how you got it? I am super new to open foam and CFD and i am learning by myself so finding difficult to underdstand

how to do it for Cylinder2D? I searched and got a formula to multiply density * velocity_X (if the flow is primarily in the x-direction). But I cannot find the density option in the Calculator in Paraview. Can you please tell me how to do it? Please reply

What are the key differences between continuously refining the mesh verses the MRF method?

Hlo Ma'am I am new to openfoam. I have to simulate single bubble rise case. I setup the case but in paraview alpha fields is not working. Can you please help me. In case if you have this case please help me with that. Humble request.

👍👍👍👍

salamalikom can you help me please at OPENFOAM

thanks a lot.

Thanks for such a nice video. My question is how I can probe over a surface not over a line or on a point? I want to know what is the airflow velocity inside a cylinder on a surface with a dimension of 50 mm x 50mm? I want to define the mean airflow velocity at the point with coordination of (195, 0, 50) on a surface with dimension of 50 mm x 50 mm around this point. The coordination of my surface around this point will be (145, 0, 0), (245, 0, 0), (145, 0, 100) and (245, 0, 100).

for me after typing tut and then cd muti…… it tells me no such file or directory note that i am on ubuntu on OpemFoam11 is there anything i am doing wrong?

Thank yo am working on something similar but please can you explain how you came about the blockMesh. Thank you once again Dr

Your openfoam tutorials have helped me tremendously in starting OpenFOAM. I am still a beginner and experimenting with a pump station where I have 3 inlets and 3 outlets. I have used pressureInletOutletVelocity in all the inlets and flowRateOutletVelocity in all the outlets. However, the model crashes with an exit code 3 after running for a couple of seconds (17s). I have posted a question regarding the problem on the CFD Online forum.I highly appreciate your help letting me know if I am doing it right.

Hi how i can make the conical cavity for bubble evolution

@Asmaa Hadane. Thank you for this wonderful video, but I want to ask if I can change the dimensions of the mesh because I tried doing that but was futile. Also I will appreciate any help I can get from the comment section as well. Thank you

Is there any way to extract data of all the time steps in one file, instead of separate files? Thank yo.

Thanks a lot ma'am

thank you for this tutorial!! Could you do a video where you explain how to set up a corner simulation of a cylinder? I tried to use MRF and SRF but I'm a bit in trouble, thanksss!!

thank you, very good tutorial!

Thanks Asmaa

Thank you for the highly informative tutorial. Is it possible to perform a simulation in openfoam for a particle suspended in air which is being sucked using Euler-Lagrange approach. I need to use the 3D cad of the particle.

habibi girl is dumbo

Thank you. Really useful. Excuse, what if the comand pvbatch doens't work? I Always get the error: "Show expects 2 arguments but 3 were given"... This issue doens't allow me to automate my Foamfiles. (Don't know if the problem is that I didn't convert them to VTK because my cases are really heavy (~GB pero case))

Hello, how i can Contact you ?

Thank you very muchhhhhhhhh

Thanks for the wonderful video. May I know how we can convert data to fluent for the CHT case where we use different folders for each fluid solid?

why my forces.dat don't have the porous force and moment?

Thanks for your videos . please post a video about 3d sphere simulation for drag coefficient. Thanks.

That was very useful. I appreciate the showing of the trace tool
