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.

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 ?
@matheusrafagnin5210Ай бұрын
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.

if you mean the volume flux it is the inlet BC for the velocity U
