GridPro 10: High-Fidelity CFD Meshing for Complex Geometries

GridPro 10 is the latest version of a world-class, specialized software platform dedicated to generating high-quality computational grids for Computational Fluid Dynamics (CFD). Developed by Program Development Company (PDC), it is renowned for its ability to produce fully automated, structured multi-block hexahedral meshes of exceptional quality, even for the most complex geometries.

What is GridPro 10?

GridPro 10 is a meshing tool designed specifically for CFD analysts and engineers who require the highest level of accuracy and mesh control. Unlike general-purpose tools that often rely on tetrahedral or polyhedral cells for complex models, GridPro 10 specializes in creating purely hexahedral (hex) grids. Hexahedral meshes are widely preferred in high-fidelity CFD for their numerical efficiency, lower dissipation, and ability to better resolve flow gradients near walls, such as boundary layers.

Core Technology: Topology-Based Meshing

The power of GridPro 10 lies in its unique topology-based approach. Instead of directly meshing the geometry, the software first constructs a “computational topology”—a logical, block-structured framework that wraps around the CAD model. The high-quality hexahedral mesh is then generated within this framework. This method ensures:

  • High Orthogonality: Cells are perfectly aligned, improving solver stability and convergence.

  • Smooth Grading: Excellent control over cell size transition, reducing numerical errors.

  • Boundary Layer Readiness: Naturally creates the ideal structure for resolving viscous boundary layers.

Key Features & Benefits of GridPro 10

1. Unmatched Mesh Quality for Complex Geometries

GridPro 10 excels where other tools struggle. It can automatically generate pristine hexahedral meshes for intricate components like:

  • Aerospace: Complete aircraft with engines, nacelles, and high-lift devices.

  • Turbomachinery: Rotors, stators, impellers, and full pumps/compressors.

  • Automotive: Full vehicle underhood flows, external aerodynamics.

  • Marine: Propellers, hulls, and appendages.

2. Automation and Speed

While offering unparalleled control, GridPro 10 also features powerful automation. Its “Autoblocks” technology can automatically generate the complex blocking topology for a given CAD model, dramatically reducing meshing time from weeks or days to hours.

3. Robust CAD Handling

The software includes robust geometry healing and preparation tools, allowing it to work effectively with imperfect CAD data from any major source, minimizing pre-processing time.

4. Scalability and Parallel Processing

GridPro 10 supports parallel processing, leveraging multiple CPU cores to generate massive, high-fidelity meshes for large-scale problems in a fraction of the time.

5. Seamless CFD Solver Integration

GridPro 10 exports meshes in a wide variety of formats, ensuring seamless compatibility with all major commercial, open-source, and in-house CFD solvers (e.g., ANSYS Fluent, STAR-CCM+, OpenFOAM, SU2).
