Hi, this may be a stretch, but I have a similar model. There's a box inside a box. But I run paraFoam I keep getting "patch 0 (start: 46000 size: 4000) name : default faces" only. Although I have many groups. Any clue?
if you don't mention the patch type like empty or wall, it will automatically create a patch called 'default faces'. Just make sure, you name all patches and mention the patch types.
Hi thanks great video. I do not why i am getting this error while trying to use snappy "Cannot find surface starting from... .stl". I have verified that the stl file is located in the trisurface folder in the constant directory. "ls" command in trisurface folder shows filename.STL, do you think it is because of difference in the filename with respect to lowercase and uppercase. In the snappyHexMeshDict; it is filename.stl while in the trisurface folder it is filename.STL ? Thanks for any help Regards
Hi, i've just started with snappyHexMesh with the 7th OpenFoam version and i have an issue about "surfaceFeaturesDict" which isn't named "sufaceFeatureExtractDict". Futhermore I can't write like that: " flange.stl { extractionMethod extractFromSurface; extractFromSurfaceCoeffs { includedAngle 150; } writeObj yes; } " I have an error about "surfaces" not found, the original script is like that: " Surfaces (“flange.stl”); includedAngle 150; " It still dark for me, if someone have an idea of how I should write it right :)
@@MechanicalModelling Okay, thank you for your reply! And thank you for a great video! Coincedentally i am working on a very similar model. I am having trouble with rounded cornes on the cubes, i.e. corners not sharply defined as in the .stl file. Do you know why this is?
@@rasmusiwersen1729 It may work if you refine the mesh or if you increase the level in explicit feature edge refinement in the snappyhexmeshdict. But I am not sure.!
Hi, can you help me with a case?

@@MechanicalModelling Thank you so much for your reply. I guess I have to define them in the changeDictionaryDict file?
@@jmpt19 I did in snappyhexmesh, check at 1:58 under geometry.
@@MechanicalModelling Thank you so much, it's solved

rename the file to .stl, don't use STL in caps. OpenFoam is case sensitive.!!

I guess that command doesn’t works anymore
@@antoine1407 I've found "sufaceFeatures" which works pretty well since :)
the ESI version (sufaceFeatureExtractDict) and CFDDirect version (surfaceFeaturesDict) of OpenFoam names the files differently.
Is this case directory available somewhere?
No. This was created for the video.
