    Hi Jerome,

    Are you asking about element Normal? In that case for Solid elements, element normal is always outwards.

    Thanks

    Rajashri,

    Not quite. Refer the picture below, I have rib structure meshed as solid elements as shown.

    I am wonder for each element, which was the direction for the E1, E2, and E3 properties as it asked to define in the MAT9OR card.

    - Jerome.

    Jerome,

    E1,E2,E3 are elastic modulus in different directions.

    As you asked about element orientation, you can review it in hypermesh by orientation review method (CTRL+F, type Normals and from the pop-up window select "Review element orientation").

    See the below image.
