A surface-mesh gradation tool for generating gradated tetrahedral meshes of microstructures with defects
2021, Computational Materials ScienceCitation Excerpt :Mesh quality can be subsequently improved by edge-swapping operations. Examples in which mesh-modification operations have been used to generate gradated meshes can be seen in Refs. [28–31]. However, such examples in the literature either do not involve multi-material interfaces, which exist in polycrystals, or do not provide enough control to concentrate the gradation at regions of interest (e.g., near defects).
