  @@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?

• 
  @Codeynamics2 ай бұрын

  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.

  Hello, thanks for the video! I was wondering if one was to try and simulate only 2 of those blades and use periodic (rotational CyclicAMI) boundary conditions would this work with the dynamic Meshing? I have been able to use rotational cyclicAMI boundary conditions with the MRF technique but have been having issues when using dynamic meshing. Thanks for any advice!

• 
  @Codeynamics5 ай бұрын

  I'm not sure if I understand your question. but here's an answer to the question as far as I understood. Regardless of the number of blades, this method can be used. There need not even be blades, you can do the same for impellers or fans or even airfoil by giving oscillating motions in the dynamicMechDict. You can customise the motion of mesh be it oscillating or rotating or periodically moving. If I haven't answered your question, please ask your question, I'll try to clarify it to the best of my knowledge. ☺️
