    TET4 is not good choice in genaral of analysis. If you have to use this type of element, you have to make very very fine mesh.

    However, with TET10 that's better. Pratically, I never use TET4 for a serious analysis with SAMCEF or NASTRAN.

    Preferences -> Meshing options -> See attached screen capture.

    You can also press the keyb shortcut 'O' for that.

    You should not choose 2nd elements while meshing because it will mess up your model

    just switch 1st to 2nd elements by panel 'order change' prior to export the deck
