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 ?
@matheusrafagnin5210 24 күн 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.

hi jozsef, Thank you for this video. Do i need to consider all this mentioned in video if i am creating mesh using salome. thank you

sir i have a doubt what is the volume parameter here. is there something where we can control the volume entering
@OpenFOAMJozsefNagy Ай бұрын
if you mean the volume flux it is the inlet BC for the velocity U

My model is a little difficult to select surface I want, I found in edit mode, press A, then press X, click limited dissolve, will get a nice and clean stl

Hi József thank you the tutorial is awesome . In your opinion can that type of moving inlet boundary condition be used with a morphing mesh (with small displacements)?

Yes

Great tutorial!, I have used the same setup files for different geometry. I'm getting this error: Reading setFieldsDict Setting volume field default values - set internal values of volScalarField: alpha.water = 0 --> FOAM FATAL IO ERROR: (openfoam-2312 patch=240220) Size 8160 is not equal to the expected length 29910 file: 0/alpha.water/internalField at line 21.

Use a fresh alpha file without the list of 0s and 1s.

is there some way to automate the 11 simulation? i think its possible to set the parameters using simple python code. but are there any thing that built in OpenFoam that allow parameteric study?

Thank you so much! I'm learning a lot from your videos. I'm new to CFD, but thanks to your videos, I've been able to improve very quickly, and I'm extremely satisfied. It seems that in Blender version 4.2, the option to select "object" in the Batch mode checkbox has disappeared. I'm curious about what role the Batch mode plays. If it's essential, it seems like using the version of Blender you're using could be an important issue for me as well. (This is just my guess, but I think that in Blender 4.2, if you don't select "Selection Only" right below "Batch," it might automatically save with "Object" selected by default)

Thank you for the input. I personally did not try 4.2 yet, so I am not sure. Possibly.

Reminded me that one of my profs said that one of his profs had a simulation in his phd that took about 6 months then one of his students done the same simulation in much less time (1 day with a more refined conditions i think) and got better results.

Can you do some Meshing for CFD using Blender tutorials? Also, how to use Blender to visualise the results of a CFD? I'm especially interested in water (in air). So Multiphase simulations showing the water shapes over weirs etc. would be great. Thanks for reading this.

I got some idea as to how we define the direction of the patch numbering based on the orientation of the surface normal vector. But let's consider the outlet patch with orientation 4 7 15 12. Is it acceptable to consider starting from other numbers (while maintaining direction) say 7 15 12 4 ?
