C12. More about solid elements

The principles stated for 2D modeling remain applicable in 3D, in particular, the use of isoparametric elements (parallelepipeds rather than tetrahedrons) is preferable, which requires a heavy and rigorous preparation of the basic geometry.

Automatic meshers should be used with caution.

Example of a bridge deck modeled using solid FE:
