Element shape functions describe how displacements vary inside a finite element. After the solid is broken into elements and element equations are written, these functions represent the internal variation of displacement within each individual element.
Conditions: Defined within an individual finite element.; Used after discretizing the domain into elements and identifying nodes.

Discretization error, also called numerical error, is the difference between the circumference of the polygonal approximation (the sum of element lengths) and the true circumference of the original continuous circle. It represents the unavoidable gap introduced when a smooth object is replaced by finite elements.
Conditions: Occurs when a continuous geometry or field is replaced by a finite collection of elements.; In the example, the comparison is between the approximated circle and the original circle.
