    Good morning!
    I would like to ask you if there is any documentation available concerning the connectivity of the second order elements created by netgen (especially TRIG6 and TET10).
    Something like this would really help me a lot:

    Thank you for your attention,

  • sorry, there's no drawing in the docu.
    I copied the following lines from the code (secondorder.cpp)
    Each row consists of 3 indices (V1 V2 E), where the edge point E lies between corner points V1 and V2.
    Please note 0-based indexing

    static int betw_trig[3][3] =
    { { 1, 2, 3 },
    { 0, 2, 4 },
    { 0, 1, 5 } };
    static int betw_tet[6][3] =
    { { 0, 1, 4 },
    { 0, 2, 5 },
    { 0, 3, 6 },
    { 1, 2, 7 },
    { 1, 3, 8 },
    { 2, 3, 9 } };
