what is cAlpha

alias paraviewWindows="touch simulation.foam && /mnt/C/Program\ Files/ParaView\5.13.0-RC1-Windows-python3.10-msvc2017-AMD64/bin/paraview.exe simulation.foam".I pasted this but does not working

Is this a backward facing step?

Thank you very much. However, when I type "notepad.exe ~/.bashrc" the message that bash: notepad.exe: command not found..." appears in the terminal. What could be the alternatives for it? Could you please suggest few ways to open notepad and trouble shoot my paraview issues.

set border lw 4 set logscale y set title "Residuals" font "arial,22" set ylabel "Residual" font "arial,18" set xlabel "Iteration" font "arial,18" set key width 1 # Loop to update the plot do for [i=0:*] { plot "< cat log | grep 'Solving for Ux' | cut -d' ' -f9 | tr -d ','" title 'Ux' with lines lw 4,\ "< cat log | grep 'Solving for Uy' | cut -d' ' -f9 | tr -d ','" title 'Uy' with lines lw 4,\ "< cat log | grep 'Solving for Uz' | cut -d' ' -f9 | tr -d ','" title 'Uz' with lines lw 4,\ "< cat log | grep 'Solving for k' | cut -d' ' -f9 | tr -d ','" title 'k' with lines lw 4,\ "< cat log | grep 'Solving for p' | cut -d' ' -f9 | tr -d ','" title 'p' with lines lw 4 pause 1 } The above script works without error

When I type the notepad.exe command, it says that the command is not found. Please help.

Does i possible to add Depth as boundary condition at the outlet of the channel. please suggest.

In Ubuntu on Windows 10: In paraview, dummy.foam presents: "ERROR: In vtkOpenFOAMReader.cxx, line 11414 vtkPOpenFOAMReader (0000022A6B98D230): \\wsl.localhost\Ubuntu\usr\lib\openfoam\openfoam2312\tutorials\RUN\cavity\dummy.foam contains no meshes.

Any suggestions are appreciated. Thanks.

Is there any difference with Openfoam 2306?

Some things to note: For OpenFOAM 11 users having issues: 1. Add "sourceInfo" without quotes above {set c0;} in topotSetDict 2. Change action subtract -> action delete in topoSetDict

Thanks for the tutorial. How can you adjust the line strengths of the generated graph by the foamMonitor function?

great tutorial. can you make tutorial on supersonic flow? or high speed flow?

This was really helpful as a new user. Thank you for your slow and clear steps.

very nice tutorial.

Can you please suggest how to do the simulation by using 2D axisymmetric geometry

Very helpful. Thanks bhai.

Hi. Could you please upload any tutorial related to biomass pyrolysis

Hi Divesh! I just wanted to express my heartfelt gratitude for the incredible work you're doing on your channel. Your tutorials on OpenFOAM have been an absolute game-changer for me. Thanks to your clear explanations and thorough demonstrations, I've been able to delve into the intricacies of OpenFOAM like never before. Thank you so much sir, your work and tutorials are really helpful. alias updated code for paraview vwesion 5.10.1 alias paraview="touch sim.foam && /mnt/c/Program\ Files/ParaView 5.10.1-Windows-Python3.9-msvc2017-AMD64/bin/paraview.exe simulation.foam"

Thank you soo much!

Is it possible to remove the mesh from any application? How will the definitions be in such a case?

please upload any boiling simulation case as soon as possible as it has been many days that you have not been seen on youtube putting any vdeo.Thanks

please do the simulation on bubble formation and microlayer thickness due to it. Thanks. Your explanation is awesome. Stay blessed.

Thank you very much sir for this very informative video. With this video, you answered many of my questions. I wanted to ask if it can be simulated when a drop of water evaporates in a system?

Thank you.

I dont really understand the right hand rule

"---> FOAM FATAL IO ERROR: Unknown patchField type parabolicVelocity for patch type patch" why do I keep getting this error. I set the type "codedFixedValue" and then name "parabolicVelocity" I dont get it :(

Is there a way I can download these tutorial files?

If I try to uninstall paraviewopenfoam510, I am forced t unintsall openfoam11 too. If I write in the terminal "sudo apt-get remove paraviewopenfoam510", I get the message "The following packages will be REMOVED: openfoam11 paraviewopenfoam510 0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded." Any advice for this?

Hi I am facing some similar issue in blockMesh. Suppose this is T-Mesh and involvs only 2 blocks. If it is a C shape mesh and I want to combine 2 blocks with one base block(Total 3 blocks). Is it possible to do that way? Or Is it compulsory to split base block into 3 blocks which will be total (Total 5 blocks in number). Kindly let me know this will help me alot.

thank you!!!!!!

Worked with ParaView 5.11. Thank you!

Hi..tnx for sharing. to view the results you can also use the Paraview installed in Windows OS. You just need to type "explorer.exe" to see where the results are stored, open Paraview and open the *.foam file you created.

Hello thanks for the tutorial. I am getting an error I can't see what the resolution is: --> FOAM FATAL IO ERROR: Unknown transport type constIso Supported transport types: 5 ( constIsoSolid polynomialSolid exponentialSolid constAnisoSolid tabulatedSolid ) file: /opt/openfoam11/etc/codeTemplates/dynamicCode/solidThermo from line 17 to line 64.

i don't know the password how to get that

I can't find the zshrc file. Could you helpe me?

can you please attach blockMesh file link. I couldn't find in telegram

following this instructions, the Paraview window open but closed automatically!! why?

In this case of blockmeshdict file you used the vof case blockmeshdict file or different one because in previous problem (vof) ncells is 24000 and in this video the ncells is 3200 . i tried thid simulation with your previous case (vof) blockmeshdict file and it is taking too much time. please guide me on this

Hi!, can we add a varible height for a block ?

Can I follow the same procedure to install ParaView on Fedora 38?

I get the errors "tar: -: Not found in archive" and "tar: C: Not found in archive" and "tar: /opt: Not found in archive" "tar: Exiting with failure status due to previous errors" Is it necessary to watch a previous video where you installed OpenFOAM in a specified directory?

Thank you so much!

Awesome video!

Help! I added zsh and must have missed a step and now cannot execute commands. How to uninstall the ZSH??

Hello, I am inclined to believe that there is an error on the RHS of Equation (2). It should be T instead of U. Anyway, I found your video useful and well-prepared! Thanks!

Yesss!!! This is what I needed.

How to create block-1 in block-0 ?

Thank You! The best!

Hi Divyesh, youre doing a great job by sharing your insights on using OpenFoam with such detailed explanations.
