Therefore, the adaptive mesh refinement method can effectively optimise the mesh distribution and obtain high-precision solutions.

... measures for the computed results are recommended. In this research the use of the Babuska/Rheinboldt error indicator in combination with linear‐elastic crack propagation problems is demonstrated. Based on this error measure an adaptive mesh refinement technique is developed. In comparison with classical...

... call these new vertices edge‐vertices(E) and face‐vertices (F) respectively (see Figure 2). For both types of new vertices, we define a separate refinement rule to determine their position. Adaptive mesh refinement Finite element Free form surfaces Mesh To perform numerical...

...A.A. Polynkine; F. Van Keulen; V.V. Toropov Presents an approach for optimal design of geometrically non‐linear structures, using adaptive mesh refinement (AMR). The optimization technique adopted is based on the multi‐point approximation method. The finite element method is used for the structural...

... to avoid oscillations in the refinement process. Two mesh optimality criteria based on: (a) the equal distribution of global error, and (b) the specific error over the elements are studied and compared in detail through some examples of application.
