Computational Fluid Dynamics (CFD)
Numerically simulate the physics of all fluid-to-fluid and fluid-to-solid interactions in your design.
Simulate Fluid Interactions
Calculate velocity distribution, density, temperature, heat transfer, pressure drop, flow rates, and fluid distribution.
Verify and Optimize
Simulate fluid distribution in electronics cooling systems to verify desired flow. Ensure your pump or fan can provide enough flow at your system pressure drop.
Avoid Part Failures
Avoid part failures and costly prototype iterations by analyzing system performance using numerical simulation before building and testing a physical prototype.

Core Software
Analyzing Complex Fluid Flows with CFD
We use physics-based simulations to solve real-world problems in fluid-flow to ensure components meet requirements early in the design cycle, saving you costly and time-consuming prototype iterations.
What is Computational Fluid Dynamics (CFD)?
Computational Fluid Dynamics (CFD) is the analysis of fluid flow and heat transfer phenomena. CFD simulates the interaction of all fluid-to-fluid, fluid-to-solid, and fluid-to-gas contact, and accounts for various fluid properties, such as velocity, pressure, and temperature.
Why Use Computational Fluid Dynamics (CFD)?
Fluid flow analysis is needed when fluid interactions play a critical role in design. CFD is a valuable tool that enhances engineering design decision-making due to its accuracy and cost-effectiveness when compared to testing physical components.
