AutoGrid5™ enables you to create multi-block structured meshes for any kind of turbomachinery, from centrifugal compressors over pumps to wind turbines. Advanced features such as cavities, sealings, gaps and fillets are also daily business for AutoGrid5™. The user is guided through the meshing process by an interactive row wizard, minimizing user input and time. As a result, a highest-quality grid is obtained, ensuring accurate CFD-results. AutoGrid5™ is fully scriptable via Python and can hence automate your workflows with ease.

IGG™ is an interactive meshing tool to manually create block-structured grids. Geometry can be imported from various CAD formats or created directly in IGG™. A block-structured mesh becomes particularly useful if the complexity of the geometry is moderate, and a high-quality mesh with full control over points distribution is required. A macro-recording function and batch mode allows to automize your workflows.

HEXPRESS™ guides the user to a high-quality hexahedral grid using 5 clearly defined steps. Flexible parameters, e.g. curvature and distance criteria, allow high control over the grid points distribution. Anisotropic refinement keeps the overall cell count as low as possible. And an inflation method for the Euler mesh allows to insert high-quality viscous layers with smooth transition.

Furthermore, HEXPRESS™ can process an initial background mesh, even a block-structured one from IGG™, which is then successively refined according the user’s specifications. As all modules of AutoMesh™, HEXPRESS™ supports python scripts, macro recording and batch mode.

HEXPRESS™/Hybrid creates hex-dominant or fully hexahedral grids for the most complex geometries. Since the geometry can be non-conformal or open, the whole CAD preparation and clean-up step is removed, saving hours or days of time per case. Multiple blocks can be meshed fully conformal, and several viscous layer techniques ensure a high-quality mesh where it really matters. A fully parallel process with high scalability, even on distributed HPC, minimizes the mesh generation time.

Poor quality CAD definitions and highly complex geometries lead to long preparation and set-up time and the need for a lot of manual input to result in a good quality mesh. It is a laborious process, making it difficult to create various design alternatives for iterative testing.

AutoSeal™ technology automates this entire process, without losing any detail of the geometry and delivers high quality meshes ready for CFD analysis in near real-time. Combined with OMNIS™/Hexpress, even the most complex geometries that used to take a week of intensive manual work to prepare now take less than a day to be fully preprocessed, including high quality meshes and without any simplification of the model.

AutoSeal™ creates automatically surfaces that fill the gaps and holes of a geometry of a given minimal hole size. AutoSeal™ works efficiently with a simple setup, even on complex geometries. It does not create a conformal geometry because it does not modify the geometry. It simply creates a set of triangulated surfaces that close the geometry

• For internal and external flow
• Independent from the application
