I don´t know how to express my frustration - but this UBUNTU is a bug, and there is a fix for it, it is called Windows.

Hello joseph, i started a new reserch project and your videos are amazing to have the hand on openfoam. I was trtying to reproduce this tutorial with the actual version of openfoam (V12). For the velocity i was able to obtain relativeley similar results. Not for the pressure. And for k epsilon and nut the values does not change after 2000 iterations. I verified all the parameters and everthing is ok. Is it a version thing ? Thanks for your response and continue with the videos without stoppin ..'that's what she said' :)

Hi Josef. The command surfaceFeatureExtract shows an error. This is what the error message reads: "The surfaceFeatureExtract utility has been superseeded and replaced by general surfaceFeature utility." It'd be great help if anyone could tell me how i can further follow this simulation as im stuck at this step. I'm tottaly new at this. I'm working on undergrad thesis about Jumping Droplet Condensation. And your tutorial has been a great help and the only helpful one i found in youtube. So im really grateful to you.

Yes the .org version breaks backward compatibility. They do it on a yearly basis. I cannot support it anymore. Please use the .com version if you want to follow the tutorials.

​@@OpenFOAMJozsefNagy yes it is the important thing but any analysis done in OpenFOAM cannot apply for industry problems. It needs too much develop. For this reason, all these studies are empty. Sorry

@@kasuora6233 Automotive industry, chemical industry, fire safety, medical industry all heavily use OpenFOAM instead of commercial codes. OpenFOAM is among the top 3 used CFD tools in the industry and among the top 5 software overall utilized on HPC clusters world wide.

Hello Sir. While listing files in pitzDaily. I got these. "karan1986@DESKTOP-389LBGP:~/pitzDaily$ ls 0 constant system" It doesn't have the same files as those were shown in your video and hence when I use rn command it gives error

hi mr jozef thanks for great works u do my question is i work on landslide simulation (landslide , water , and air) solving with multiphaseInterFoam solver ofv2012 how can plot average velocity for only landslide its is possible? what U represent in this simulation a mixed U ?

Very informative video Mr. Nagy! When i tried to rerun the simulation with the altered mesh, i got an error for "negative initial temperature". That mistake goes away when i change the mesh baack to its original format. Any idea why that is? I would appreciate any help.
