    ​@@Codeynamics Today I followed the tutorial and succesfully did the meshing. I am also thinking to run the case considering a random velocity of fluid. I must again thank you for making everything as clear as possible. I was wondering if you can make a tutorial meshing the same file in "cfMesh" . Also, can you make any tutorial on meshing and case setting a wind turbine!

    thanks really helpful.Just a quick question did you run the silulation and if so which command did you use?

    Thankyou. I did not run the simulation. If you had to run for that case specifically, you should be using simpleFoam command. It depends on the solver. Please do subscribe and support for more useful videos.

    @@Codeynamics hello again, i'm having a problem with the snappyhexmesh.When i run it i am usually having blocks meshed around the airplane instead of the geometry being meshed completly.So the resulting mesh is just a bunch of blocks surrounding the aircraft what can be causing this error?I just used the snappyhexmesh command without the mpirun because for some reason it told me that this command doesn't exist could this be the reason?

    The reason is that in the snappyHexMeshDict, under snapControls function, see the 6th and the 7th parameters. set the implicitFeatureSnap to false and set explicitFeatureSnap to true. This should make your problem solved. The behavior with just snappyHexMesh will be exactly the same as doing it with decomposed case. It is only a matter of time that differs for both the process. mpirun case is faster due to parallel processing. I hope this is clear.
