What is Computational Fluid Dynamics (CFD) Software?

Computational Fluid Dynamics or CFD is a technique that deals with the solution of fluid flow fields through numerical analysis. SOLIDWORKS Flow Simulation is a CFD software designed for the everyday SOLIDWORKS user and analyst. It provides dynamic feedback on the fluid flow and Thermal performance of their products. With Parametric optimization capabilities, users can automate the design and analysis process to discover the best iteration of their design within the familiar SOLIDWORKS CAD environment

“…exceptionally knowledgeable and professional in helping customers as well as demonstrating the full potential of the software and background information.”

Simulate Fluid and Gas Flow

Flow Simulation enables users to simulate a wide variety of liquids and gases for different engineering scenarios. A few common applications are flow through manifolds, heat exchangers, electronics cooling and aerodynamics. Check out the videos to see some examples of fluid flow and heat transfer situations in SOLIDWORKS Flow Simulation.


SOLIDWORKS Flow Simulation

Premier CFD Analysis Tools to ensure quick and accurate results of your 3D CAD Designs

FEA Integration
System level design requires optimizing for fluid behavior and material strength. Because SOLIDWORKS incorporates CFD analysis and FEA, designers can incorporate both with the FEA transfer from SOLIDWORKS Flow Simulation. This allows Engineers to use the resulting force and heat transfer effects from their CFD analysis as the load inputs in their FEA analysis to fully understand the structural behavior based on the fluid behavior.

Rotating System Analysis
Coming up with optimal designs for systems with fan blades or impellers is impossible without accurate results. SOLIDWORKS Flow Simulation provides users with tools that allow for rotating regions and sliding mesh methods to accurately simulate the behavior of these types of systems based on geometry, angular velocity, and transient behavior of the fluid.

External Flow Analysis
External analysis is used when we need to understand the fluid behavior around our model based on the environment conditions. Wind Turbines, Airplanes, ships, heat sinks, and automobiles would all be studied using external flow analysis. In External studies, the computational domain acts as our virtual wind tunnel with boundary conditions, heat sources, and transient behavior all applied through the user friendly setup wizard.

Internal Flow Analysis
PCB enclosures, valves, pumps and manifolds are all examples of internal analysis studies. Because SOLIDWORKS Flow Simulation functions inside of SOLIDWORKS, setting up computational domains, boundary conditions and heat sources can be done in minutes. The results of your analysis can be applied directly to your design allowing you to test more iterations in less time.

Free Surface Dynamics
Free surface is a condition with a freely moving surface between two fluids that don’t mix such as air and water. Using the Volume of Fluids approach, we can accurately simulate transient conditions such as tank sloshing or any open bath fluid behavior. Not only can these test give us a better understanding of what the fluid is actually doing in the system, but we can also gather useful quantitative results such as force or pressure on internal walls.

Electronics Cooling Module
An add-on for SOLIDWORKS Flow Simulation, the Electronics Cooling Module (ECM) provides additional materials and material models that are specific to circuit board and PCB enclosure analysis. The Two-Resistor component model is a JEDEC approved method for simulating chip temperature such as BGA, QFP, QFN and SOP. The PCB-generator understands layer properties to provide an accurate orthotropic thermal behavior. Joule heating capabilities mean designers can apply current as the input to estimate heat generation.

Particle Study
For certain applications the fluid in a design might contain solid or liquid particles. The behavior of these particles and the fluid that interacts with them is critical to the function and efficacy of your system. With particle studies in SOLIDWORKS Flow Simulation we can analyze the particle behavior and see results for erosion and accretion of the system and the particle based on material properties, mass flow rate and other physical characteristics of the system design.

Parametric Optimization
SOLIDWORKS Flow Simulation is a robust and complete CFD analysis tool. But it’s integration into SOLIDWORKS CAD means it’s also a powerful design tool. This integration also opens the doors for optimizing your parameter-driven design based on the iterative results of the CFD studies and user-defined goals for the results.

HVAC Module
Accurately understanding HVAC systems is a complicated task. That’s why SOLIDWORKS created the HVAC add-on module for SOLIDWORKS Flow Simulation. This tool provides additional capabilities such as advanced radiation which modifies the way radiation between bodies, including semi-transparent materials such as glass, is calculated to provide higher fidelity of result information. The tracer study function allows the simulation of pollutants in a volume and shows how and where that pollutant will disperse in an environment.
