The most detailed type of model uses SOLID elements to fully capture the geometry of cast, forged and machined components, and give the best stress accuracy.

The latest generation P-type analysis software is particularly effective. It uses geometric elements, which mirror the underlying CAD surface geometry - enabling stress concentration features such as fillet radii and welds to be accurately modelled. The P-type solver also selectively increases the polynomial order of the elements to converge to a pre-defined tolerance. The resulting stress accuracy is of a sufficient quality to allow precise fatigue life predictions.
