Fidelity Pointwise: Unstructured Voxel Block Best Practices

In this quick tutorial, we cover best practices and advanced settings for unstructured voxel blocks in Fidelity Pointwise, using the ONERA M6 wing as an example. Unstructured voxel blocks combine the advantages of voxel meshing and unstructured meshes, enabling smooth hierarchical refinement while maintaining flexibility at far-field boundaries. In this video, you’ll learn how to properly set minimum and maximum voxel edge lengths, background spacing, and advanced solver settings to achieve a clean, efficient far-field mesh—without over-refined islands or poor transitions. 🚀 What You’ll Learn: - What unstructured voxel blocks are and when to use them - Key differences between pure voxel blocks and unstructured voxel blocks - How voxel refinement works using powers of 2 for smooth transitions - How to choose minimum and maximum edge lengths based on mesh resolution - Best practices for background spacing in voxel solvers - How to eliminate over-refined voxel islands near leading edges - Applying advanced voxel block settings in Pointwise for CFD workflows Perfect for CFD and aerodynamic engineers looking to improve volume mesh quality, far-field meshing, and solver robustness. 👍 Like, subscribe, and comment for more CFD meshing tutorials. ________________________________________________ FOLLOW US LINKEDIN: https://www.linkedin.com/showcase/cadence-cfd X: https://x.com/CadenceCFD BLOG: https://community.cadence.com/cadence_blogs_8/b/cfd
