(200,000 Tetra’s/min) GTS’ Tetra Mesher is capable of including holes, curves and points that are present in/on the solids. Mapped Mesh Generation GTS’ Map Mesher generates the structured (regular orthogonal) mesh both in the surfaces and solids. Mapped Solid Meshing GTS’ Solid Map Mesher generate hexa and/or penta mesh in simple solids by full mapping or combination (auto+map). Size Control GTS provides various size control methods, uniform size, division, linear grading (size ratio and symmetry option) and refinement option. Size Control GTS provides adaptive seeding function based on user-specified mesh size and geometric characteristics (curvature and feature).
