| Matrix or Vector | Shape Functions | Integration Points |
|---|---|---|
| Stiffness Matrix | Linear in x, bilinear in y and z directions | 2 x 2 |
| Load Type | Distribution |
|---|---|
| Element temperature | Based on element shape function, constant through the direction perpendicular to element plane |
| Nodal temperature | Same as element temperature distribution |
