Automated Fullly Hexahedral Grid Generation

AutoGrid v5 brings a new graphical interface, allowing to mesh any kind of radial or axial single/multistage rotating machinery in minutes.

AutoGrid^TM is a highly automatic, fully hexahedral grid generator for rotating machinery. It allows designers and engineers to mesh complex axial, radial, and mixed-flow configurations with a single click.

AutoGrid v5 brings increased flexibility in grid topology. From left to right: user-defined topology, butterfly tip gap mesh, splitter blades, or tandem configuration.

Key features include:

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.
