Abstarct. An improved method using feature line extraction is described for automatically generating hexahedral meshes for complex geometric models that automate the normally interactive operations (such as model editing). Testing showed that the time taken for these interactive operations was significantly reduced, making it possible to quickly generate hexahedral meshes with sufficient qualit...

Many problems in engineering, chemistry and physics require the representation of solutions in complex geometries. In the paper we deal with a problem of unstructured mesh generation for the control volume method. We propose an algorithm which bases on the spheres generation in central points of the control volumes.

With high-order methods becoming increasingly popular in both academia and industry, generating curvilinear meshes that align with the boundaries of complex geometries continues to present a significant challenge. Whereas traditional low-order methods use planar-faced elements, high-order methods introduce curvature into elements thatmay, if added naively, cause the element to self-intersect. O...

A mesh is a discretization of a geometric domain into small simple shapes, such as triangles or quadrilaterals in two dimensions and tetrahedra or hexahedra in three. Meshes nd use in many application areas. In geography and cartography, meshes give compact representations of terrain data. In computer graphics, most objects are ultimately reduced to meshes before rendering. Finally, meshes are ...
