    I am on the last lecture oh the DTH-hull, i have run all command according to recture.

    It runs good till decomposePar.

    but when I proceed for snappyHexMesh it gives following error

     

    Checking mesh with layer …
    Checking faces in error :
    non-orthogonality > 70 degrees : 136
    faces with face pyramid volume < 1e-13 : 0
    faces with face-decomposition tet quality < 1e-30 : 0
    faces with concavity > 80 degrees : 0
    faces with skewness > 4 (internal) or 20 (boundary) : 0
    faces with interpolation weights (0..1) < 0.05 : 0
    faces with volume ratio of neighbour cells < 0.01 : 0
    faces with face twist < 0.05 : 0
    faces on cells with determinant < 0.001 : 0
    Detected 136 illegal faces (concave, zero area or negative cell pyramid volume)
    Extruding 0 out of 493 faces (0%). Removed extrusion at 0 faces.
    Added 0 out of 1479 cells (0%).

    Doing final balancing

    could you tell me your blockMesh number and which decomposePar option do you use before snappy? please post which commands did you use one by one and what kind of feedbacks you get?

    first command blockMesh, second surfaceFeatureExtrsct, no any error.

    now I will post all my commamnd and decompose par setup
