AutoGrid^TM is a full automatic hexahedral grid generator for all type of rotating machinery: complex axial, radial, and mixed-flow configurations.

The wizard based interface brings increased flexibility in grid topology. From left to right: user-defined topology, butterfly tip gap mesh, splitter blades, or tandem configuration.

• Optimized topologies according to geometrical configurations;
• Automatic grid points distribution according to user's grid size requirements;
• Free user-defined topologies;
• Advanced smoothing algorithms yielding a high grid quality;
• Multistage and bypass configurations;
• Capturing a large range of geometrical features, such as tip and hub clearance, seal-leakages, rounded and blunt leading and trailing edge, spinners, flow path discontinuities, rotor/stator, inner/row interfaces, non-axisymmetric end walls, bleed ports, cooling holes, tip basins, part-span shroud, etc.
• Grid wake refinement;
• Full connectivity with IGG^TM (NUMECA's general structured multiblock grid generator), allowing to interactively mesh up- and downstream components such as nozzle, volute, ducts, condensers, etc.;
• Advanced template and script technology for automated meshing of features such as fillets, leakage paths, cavities, etc.
