... calculations, it is not common for finite element solvers to use such wall distance calculations. The results presented here clearly show that the proposed methods are suitable for unstructured meshes and finite element solvers.

... particle methods provide a unifying framework for both discrete and continuous systems, the program is based on the parallel particle mesh (PPM) library, which has already been demonstrated to provide transparent parallelization and state‐of‐the‐art parallel efficiency using particle methods for continuous...

... to be incompressible, which leads to the volumetric locking phenomenon, when using a low order finite element approximation in the solution of plane strains and axisymmetric problems. This phenomenon is also verified in mesh‐free methods, as seen in Askes et al. (1999) , Dowbow and Belytschko (1999...

... probabilistic aspects of heterogeneities. Design/methodology/approach The paper shows how to construct the structured FE mesh representation for the failure modelling for such structures, by using a building‐block of a constant stress element which can contain two different phases and phase interface. All...

... ; Liu and Gu, 2003). Because the local meshless methods do not require a global background mesh for the numerical integration of the global weak form, they are truly meshless and have been widely used. Hence, the local meshless technique will be used in this paper. The nonlinear dynamic system...

... data are: length 200 mm, width 100 mm, two arc radii 20 mm and 12.5 mm, mesh of this part is composed of 1,035 nodes and 1,932 triangular elements (Figure 7(a)). Based on the UG OPEN/API technology, an application software picking‐up this mesh is developed, and a reference point (0, 0, 0) is chosen...

... problems, the deformation gradient tensor can be evaluated invariably using either isoparametric or metric shape functions. The developed elements are found to exhibit improved performance in the presence of mesh distortions. Research limitations/implications The numerical problems in this paper...

...J.T. Hong; Y.K. Lee; S.R. Lee; D.Y. Yang Purpose In the finite element analysis of a hot forging process with hexahedral elements, flash region is difficult to analyze because of the thin shape. In this paper, a hot forging process is effectively analyzed by constructing a locally fine mesh...

... The saving would be even more significant if this mesh adaptation technique were applied in three dimensions. Indeed, in 3D problems, the computing cost is vital and, in general, it is this cost that sets the limits. Practical implications This tool is directly usable in the design stage. Originality...
