Geometric symmetry idealization
simplification of system geometry from 3-D to 2-D or 1-D
an entire class of geometric features is modified in the analysis model representations. For example, all hexagonal bolt heads are represented as cylinders in an analysis model.
modeling idealizations related directly to geometry of the physical system being modeled
These classes describe the various phenomenon associated with continuum mechanics models. This may include phenomena such as fluid flow, heat conduction, elasticity, electromagnetics, etc.
An individual geometric feature of the physical system is suppressed, i.e. not included, in the analysis model
Empirical_ model
Empirical models are based entirely on experimental data, i.e. observations of physical system behavior.
The shape of the physical domain is altered in the analysis model representation
This is the quantiity on which this phenomenon is based.
