Product Overview

Autodesk CFD Ultimate is a computational fluid dynamics platform for simulating 3D fluid flow, heat transfer, and thermal effects in product designs. It combines incompressible and compressible flow analysis, steady-state and transient thermal modeling, and advanced geometry management in one integrated simulation environment for engineers validating product performance before manufacturing.

CFD Ultimate extends core CFD capabilities with rigid body motion simulation, enabling analysis of moving objects such as impellers, pumps, and rotating machinery interacting with surrounding fluids. The software serves mechanical engineers, HVAC designers, thermal engineers, and product development teams validating fluid dynamics, heat transfer, and thermal behavior in automotive, electronics cooling, HVAC systems, aerospace applications, and industrial equipment design workflows.

Autodesk CFD Ultimate Key Features

• 3D Fluid Flow Simulation: Analyze 3D incompressible and compressible fluid flow through complex geometries to predict velocity distribution, pressure drops, and flow patterns in pipes, ducts, and cavities.
• Thermal Analysis and Heat Transfer: Simulate conduction, convection, and radiation heat transfer in solids and fluids to calculate temperature distribution and identify thermal bottlenecks in product designs.
• Steady-State Flow and Thermal Analysis: Run equilibrium simulations to rapidly evaluate design performance under constant operating conditions and compare multiple design iterations without time-stepping overhead.
• Transient Flow and Thermal Analysis: Analyze time-dependent behavior with accurate time-history results to model startup conditions, dynamic thermal response, and unsteady flow phenomena in systems.
• Rigid Body Motion Simulation: Simulate interaction between moving solid objects (impellers, rotating shafts, sliding components) and surrounding fluid to analyze pump performance, motor cooling, and machinery thermal effects.
• Free Surface and Two-Phase Flow Modeling: Model dynamic interfaces between liquids and gases to analyze sloshing, tank filling, water-air mixing, and multi-fluid heat exchanger performance.
• Advanced Meshing and Geometry Tools: Create tetrahedral and hexahedral meshes with adaptive refinement, boundary layer meshing, and automatic volume extraction from CAD geometry for accurate flow domain definition.
• Radiation Heat Transfer Modeling: Include radiation as fundamental heat transfer mode alongside conduction and convection to accurately model thermal effects in high-temperature systems and open-space cooling applications.
• Real-Time Results Visualization: Display velocity magnitude, pressure, temperature, and turbulence fields as contour plots, vector plots, and isosurfaces with interactive cutting planes to interrogate results at any location.
• Flow Rate and Pressure Analysis: Calculate mass flow rate, volume flow rate, and pressure drops across inlets and outlets to verify system performance and predict pressure-velocity relationships.
• Temperature Field Interrogation: Extract point and plane sampling results to identify hot spots, verify uniform temperature distribution, and correlate thermal data with structural or electrical stress analysis.
• Multi-Physics Integration: Couple CFD thermal results with finite element structural analysis to calculate thermally-induced stresses and deformations for comprehensive product validation.
