The p-method solution option offers many benefits for linear structural static analyses that are not available with the more traditional h-method, discussed elsewhere in this documentation. The most convenient benefit is the ability to obtain good results to a desired level of accuracy without rigorous user-defined meshing controls. If you are new to finite element analysis or do not have a solid background in mesh design, you might prefer this method since it relieves you of the task of manually designing an accurate mesh.

In addition, the p-method adaptive refinement procedure offers error estimates that are more precise than those of the h-method, and can be calculated locally as well as globally (for example, stress at a point rather than strain energy). For example, if you need to obtain highly accurate solutions at a point, such as for fracture or fatigue assessments, the p-method offers an excellent means of obtaining these results to the required accuracy.
