Overview of Autodesk CFD
Autodesk CFD (Computational Fluid Dynamics) is a powerful software tool designed to help engineers and analysts predict and analyze the behavior of fluids and gases in various engineering applications. Here’s a detailed look at what the product does and its key features.
What Autodesk CFD Does
Autodesk CFD enables users to create simulations that predict how liquids and gases will perform under different conditions. This capability is crucial for optimizing designs, improving performance, and ensuring safety in a wide range of industries, including architecture, engineering, manufacturing, and construction. The software allows users to simulate fluid flow, heat transfer, and other thermal phenomena, providing valuable insights that can guide design decisions and enhance product efficiency.
Key Features and Functionality
Simulation Capabilities
- Fluid Flow and Heat Transfer: Autodesk CFD can model multi-component fluids or gases, handling both steady and unsteady flows. It supports incompressible and compressible flows, with the advanced solver capable of handling high-speed flows with varying fluid densities.
- Free Surface Modeling: The software can dynamically simulate the interface between liquids and gases, modeling phenomena such as waves, sloshing, and spilling. This is particularly useful in architectural and engineering applications.
CAD Integration
- Seamless CAD Connections: Autodesk CFD integrates seamlessly with Autodesk CAD tools like Inventor, Revit, AutoCAD Architecture, and AutoCAD MEP. This allows for direct import of CAD models and automatic assignment of simulation settings, reducing setup time for subsequent design iterations.
Meshing and Geometry Tools
- Surface Wrap and Meshing: The software includes a surface wrap tool to consolidate multiple bodies of a model, add external volumes, and generate high-quality meshes. It also supports adaptive mesh sizing and the import of existing meshes from various formats.
- Wall Layer and Prismatic Layers: Users can activate the wall layer option to achieve prismatic layers in the boundary layer of solid surfaces, which is essential for turbulence modeling.
Advanced Analysis Tools
- Motion Simulation: The motion solver module analyzes the interaction between solid objects in motion and the surrounding fluid, including fluid-driven or prescribed motion. This is useful for analyzing flow-induced forces and the effects of motion on fluid behavior.
- Custom Result Calculations: Users can set up custom result quantities to analyze and visualize quantities beyond standard CFD results. Tools like particle tracing, iso surfaces, and cross-sectional planes help in visualizing and interpreting simulation results.
- Wall Calculator: This tool calculates flow-induced forces on solid and wall surfaces, including heat flux and wall temperature, providing detailed insights into the performance of designs.
High-Performance Computing
- Remote and Cloud Solving: Autodesk CFD supports running simulations on remote computers, clusters of computers, and even cloud data centers using cloud credits. This allows for high-performance computing without tying up local resources.
- Scalable Solver: For large simulations with over 10 million elements, the scalable solver optimizes cache performance by running each process on multiple threads.
Collaboration and Results Analysis
- Result Extraction and Visualization: The software includes tools like the new result extraction tool, cut regions, and improved graphical performance to enhance the analysis and visualization of simulation results. Users can also export CFD results to FEA tools for further analysis.
- Autodesk CFD Viewer: This tool enables collaboration across multiple engineering workgroups by presenting and sharing graphical results.
In summary, Autodesk CFD is a robust tool that offers a comprehensive set of features for simulating and analyzing fluid flow and heat transfer. Its integration with CAD tools, advanced simulation capabilities, and high-performance computing options make it a valuable asset for engineers and analysts across various industries.
