From CFD/FEA results to visual analysis

Import simulation results from widely used CFD and FEA solvers. Easily and accurately visualize scalar, vector and tensor data using a large set of visualization tools including: iso-surfaces, cross sections, boundary views, colored vectors, animated particles, line integral convolution, illuminated stream lines, stream ribbons, and advanced volume rendering. Work with 2D or 3D regular and unstructured meshes. Handle any combination of tetrahedron, hexahedron, wedge and pyramid cells. Display results on selected boundaries. Filter elements by region or by material. Select which fields to load. Handle fields defined per node or per cell.

Analysis, visualization and feature extraction tools

Accurately isolate regions of interest where secondary variables, surface and volume integrals, and arithmetic functions will be computed. Use interactive probing to get the exact values at a given location or along a given line. Extract advanced features such as critical points or vortex core lines. Seed particles or stream lines from specific locations. Accumulate computation results in spreadsheets and curves. Use ready-to-use computation modules such as enstrophy, vorticity, Mach number, etc.

From 3D imaging to simulation

Instead of using virtual models coming from CAD systems, it is now possible to scan real objects using CT scanners. The result of the scan process is a stack of images that can be pre-processed to generate 3D meshes used as input to a CFD/FEA solver. Avizo’s advanced segmentation, labeling, filtering, surface reconstruction and tetrahedral mesh generation tools can be used to produce high-quality meshes that can be exported to CFD and FEA solvers to run the simulation. The resulting data can be re-imported for visualization and analysis using Avizo post-processing tools.

Fast and easy to use

Benefit from Avizo’s sophisticated user interface to navigate your 2D and 3D meshes. The easy-to-use 3D manipulation tools allow you to precisely locate specific regions of interest. Repetitive tasks can be automated using template networks or scripts.

Scalable architecture

Take advantage of multi-core systems for faster computation and display on very large models. Avizo Wind has been specifically designed to support multi-core architectures for maximum computation performance.
