This use case explains how you can convert CFD simulation results from Ansys Fluent into OpenUSD format for advanced visualization in NVIDIA Omniverse.
Audience and persona
- Primary users: CFD engineers, visualization specialists, and Python developers
- Industry: Any
- Prerequisites: Installations of Ansys Fluent, PyFluent, and NVIDIA Omniverse
Problems
- Postprocessing CFD results in traditional tools limits interactive visualization and collaboration.
- Engineers need a way to export simulation data into a modern, interoperable format for advanced rendering and analysis.
- Desktop applications must be configured significantly to interact
Solution
Use PyFluent to extract simulation data from Ansys Fluent and export it to an OpenUSD format file, which enables rich visualization workflows in Omniverse using Universal Scene Descriptors (USDs).
Benefits:
- Seamless integration between simulation and visualization environments
- Enables collaborative, real-time rendering of CFD data
- Supports advanced material and color mapping for better insights
Features and capabilities used
- PyFluent: Access Fluent solver session and field data using scripting
- USD Python bindings: Create USD scene, geometry, and attributes
- Omniverse integration: In Omniverse, use USDs for visualization
