Abstract. In finite element analysis (FEA), meshes are typically used to represent object geometry for simulation and analysis. Meshing is an essential FEA process that can affect the accuracy and computational efficiency of a solver considerably. Tetrahedral meshes are commonly used because they can be generated automatically, but they have low accuracy and a high number of meshes is required to describe a given object shape. In particular, tetrahedral meshes are unsuitable for representing thin or corner areas. By contrast, hexahedral and prism meshes are characterized by higher accuracy, convergence, and application specificity, rendering them more preferable to tetrahedral meshes. However, hexahedral and prism meshes are inherently more complex and difficult to generate.
