Such a wonderful wonderful explanation of blockMesh. Thank you.

[@DDFluids]

Thanks. Keep learning :)

[@volkanatar4232]

I dont really understand the right hand rule

[@fundamentalsofmechanicalen2168]

Nice lectures please upload more lectures

[@DDFluids]

Sure. Please share with others too. :)

[@fundamentalsofmechanicalen2168]

Sure.... You do good job.....

fourth option: hex (4 5 6 7 0 1 2 3) means the first face is 4567 whose normal points out of the bounding box. One should choose the first face in that order where the normal to that face points towards the inside of the bounding box. Hence, hex ( 4 7 6 5 0 3 2 1) would have been correct.
Similarly, fifth option: hex (4 5 1 0 6 2 3 7) is incorrect because the first points of first and second face don't correspond to each other, i.e., 4 doesn't correspond to 6. Instead hex (4 5 1 0 7 6 2 3) would have been a correct choice.
Still, quite not sure about the sixth option. The video says wrong direction but it seems it is incorrect only because the normal to first face points outside of the bounding box.

Hai brother . if any of axes are at centre of the cube.then how to write block.hex ? ....help me in this basic concepts

[@aimannorsham3557]

Sir, how to do a triangle geometry by applying the concept that you mentioned on this video?

[@nikasarabi1275]

are the starting point in defining boundaries like front and back face or walls important? or the only important thing is the orientation?

[@sandipgewali641]

I installed openfoam10 and paraview was installed by default. However, when using of2206, the paraFoam command doesn't work. Should I install paraview again or can I use the paraview that was supplied pre-compiled openfoam10 ??

whats the difference between patch and face in the codes above

[@DDFluids]

Every side is a face in general mathematical explanation. Whereas patch is a type of the face that we define in CFD.
