Table 3.17 shows key features of the base element (shell).
| Table 3.17 | |
 | |
| Feature | Description |
| Reference points: | A: bottom of side walls. |
| Local shell coordinate system (LCS): | Axis X: transverse axis of plate; Axis Y: transverse axis of plate; Axis Z: normal axis to plate. |
| Orientation in WCS: | All axis can be horizontal and vertical according to the shell options:  Additionally, can flip the element relative to its plane to simulate the bottom plate of the pressure vessel. |
| Shell constraints (dof): | Point A. All calculations by the finite element method (FEM) fix bottom of side walls. |
| Shell loads: | Inner overpressure. Outer pressure. Hydrostatic pressure. Thermal strains. |
