FEA and CFD Simulations
Finite element analysis (FEA) and computational fluid dynamics (CFD) are both used for computer-aided engineering (CAD) to solve incredibly complicated problems.
Both FEA and CFD simulations are used to validate designs and optimize them to ensure that quality, performance, and safety standards are met, even before the materials are cut and assembled. Widely accepted as the best simulation option for real-world situations, both FEA and CFD are constantly evolving. Both are great for optimizing design solutions prior to potential problems. Both types of simulation can also help ensure products are better, safer, and cost less to produce.
But which solution is better, and for what use?
FEA Simulation Strengths and Advantages
FEA is commonly used to assess the strength and quality of a design. For instance, this form of simulation can be used to see what is likely to happen if a motor vehicle is in an accident, particularly in terms of the outcome for driver and passengers. The simulated results can then be used to design safer cars.
FEA enables us to consider various “what if” scenarios to see if, for instance, different materials might be lighter, stronger, or more cost effective that the materials used in the existing design.
CFD Simulation Strengths and Advantages
CFD simulations are commonly used to calculate the path of fluid flow of a gas or liquid, and to see how it reacts to any objects it might encounter on its path. Analysts using CFD simulations can also determine forces that fluids project onto objects in its path, and by using these values, determine how the fluid affected the structure of the object.
So, for instance, a CFD simulation might test the airflow over a car to ascertain how it cuts through wind, and ultimately have aerodynamic and fuel-efficient it is. The CFD simulation can also measure the effect of design changes to see if they will improve aerodynamics and fuel efficiency.
Used together, the CFD study can determine the forces of fluid projected onto objects and use this data for another FEA study to determine how objects were affected.
The MESH Approach to FEA and CFD Simulations
MESH Automation uses exceptionally sound advanced engineering principles, advanced analytical tools, modern software and the correct instrumentation to solve problems and develop long lasting solutions with the highest value.
Our analytic expertise and experience in FEA and CFD simulations is extensive and varied:
- FEA Analysis. We use SolidWorks Premium for FEA analysis of parts and assemblies and have several engineers with substantial experience and training in this area. This is particularly useful when we are designing high-speed machinery or systems that are load-sensitive such as robot end-of-arm tools or fast automation cells. We can also analyze customer designs and provide invaluable feedback.
- CFD Analysis. We use computational fluid dynamics software by SolidWorks to analyze airflow and make structural changes in nozzles, hoods, and forming chambers. This analysis technique helps us maximize the process efficiency by eliminating dead spots, predicting velocities more accurately, and making design changes that reduce the overall equipment costs. When used properly, CFD can bring real value to your process and project.
- Simulations. We have engineers who are dedicated and specifically trained to conduct robot simulations for ABB, FANUC, Epson, Omron Adept and Motoman robots. Our investment in software and training in this field has proved to be very valuable to our business and our customers. In addition, we use SolidWorks simulation software to simulate entire automation cells moving, assembling and doing what they were designed to do. This type of in-house simulation is not only valuable for our design team, but can also be useful for presentation purposes.
