The adaptive method implemented is the H-method.
At constant element order, the mesh is selectively refined (decrease element size) in such a way as to obtain a desired results accuracy. The mesh refining criteria are based on a technique called predictive error estimation, which consists of determining the distribution of a local error estimate field for a given static analysis case (without multi loads).
As a result, the use of the adaptative method makes it possible to reduce the memory costs and the time costs.
