Accurate analysis predictions rely on knowledge of three sets of information:

GEOMETRY. This can be supplied from 3D CAD data or constructed within the analysis package. The accurate modelling of features such as fillet radii for example is critical to the accurate prediction of stresses.

LOADINGS. The model must be realistically constrained in a way which corresponds to the boundary conditions it will see in use. Loadings can be applied to test specifications if known, or recovered from data acquisition.

MATERIAL. Material properties can be assigned to published data or derived from correlation with tested parts.
