    I have created fixed wing aircraft for simulation.  I have run blockMesh, and snappyHexMesh, it run perfect.

    but when I give sanppyHexMesh command it run for the 1 and half hour. but then following error come.

    what is the solution for this.

    Hi,

    You said blockMesh and snappyHexmesh worked well then you showed an error during snappyHexMesh ?

    Error says during boundary layer it creates negative cell… Before going to bounday layer stage can you paste here surface mesh how does it looklike? And did you check the .stl surface quality of wing.stl?

    sorry I mean blockMesh and surfaceFeatureExtract rubs succssecfully.

    and snappyHexMesh runs for the one and half hours, and then this error comes.

    when I change the first layer height. the wing get meshed.

    but when Decompose the mesh with hierarchical method and run the simulation them following error come.

    Your simulation is diverged.

    Can you decompose with scotch for running and let me know result.
