In this paper, we introduce a posteriori error estimators to guide dynamic mesh adaptivity and to determine a novel stopping criterion for the fixed-stress split algorithm to improve computational efficiency. Previous studies for flow coupled with geomechanics have shown that local mass conservation...

... reservoir models. Initially, model stored in 2.5D geometry format is loaded into memory as a 3D unstructured gird. Then, visualization is based on a preselection of the data needed to construct the model representation from an unstructured mesh. The key component of this workflow is an efficient algorithm...

... on supporting, or at least containing, the ground between rockbolts using what is referred to as local, surface, or areal ground support. Steel mesh, in various combinations and with other components, is often used to accomplish this, as well as to retain loose rock. Local ground support is an integral part...

... ABSTRACT: In this work, the suitability of several meshing strategies to optimize the CPU time consumption is investigated. The mesh sensitivity strategy is established by applying the basic framework of a coupled hydro-gas-mechanical 3D FEM numerical model to simulate the tests in terms...

... simulation is adopted to computational fluid dynamics (CFD) technique, including overset mesh, adaptive mesh. The experimental result verifies the validity of the numerical method. The numerical results show that the influence of the cable's shape cannot be simplified, which produces some unstable forces...

... When seismic data are acquired over an irregular topographic surface, honoring topographic variations poses challenges to existing modeling algorithms. To deal with the challenges, the mesh-free scheme is introduced to seismic modeling with surface topography because of its two advantages. First...

..., small-scale cracks) are the target waves used for imaging. Since the ballastless track is reinforced with steel mesh, those target waves tend to be distorted or even overwhelmed by the undesired diffraction from reinforcing steel bars. In this case, some processes (e.g. layer tracking, defect...

Because a local mesh only serves one measurement station at one frequency (or time channel), it can be rapidly solved, and the parallelization is easy as no communication is needed between local meshes. In our present work...
