    Iam simulating one UAV and get this error.

    what is the solution

    Hi Srinivas,

    May I know which lesson is this from?

    Please elaborate on your question.

    this is not from the lesson.

    i take one geometry of UAV,  and run surfacefeatureextract, then blockMesh, they run successfully

    but when i run snappyHexMesh it run for half hour then above error came “killed”.

    did you checkyour memory???

    Then can you decrease refinement level a bit and try to create very coarse mesh then we can understand that your memory is enough to create mesh or not
