The Fluid Dynamics Engineer Role on the 3DEXPERIENCE Platform allows users to select between three turbulence models: Spalart-Allmaras, SST k-ω, and Realizable k-ε. In this article, we'll break them down to help you gain a better understanding of the differences between them and the strengths and limitations of each. 


The 3DEXPERIENCE Fluid Dynamics Engineer role (also referred to as FMK) is a high-power tool that allows the user to create, modify, and run Computational Fluid Dynamics (CFD) simulations. The Fluid Dynamics Engineer role is a general-purpose CFD tool that works in the 3DEXPERIENCE environment, allowing users the benefits of cloud storage, cloud computing, and cloud collaboration.

Unlike familiar Windows folder-based systems, files on the 3DEXPERIENCE platform are not organized into folders but into a single collaborative space. There are many benefits to storing data in this manner, including faster retrieval, optimization of resources, and more. However, one of the side-effects is potentially problematic navigation to saved files. 


SOLIDWORKS Flow Simulation is a powerful tool used to simulate numerous fluid scenarios including recirculating flow. Recirculating flow is used in various applications, from the working fluid in nuclear power plants to coolants in automobile engines and electronics. To make the correct design decisions, one must understand the behavior of flow and heat transfer. Using the tools in SOLIDWORKS Flow Simulation can help make these critical decisions in the design of recirculating flow systems. 


So, you want to use 3DEXPERIENCE with parts modeled in SOLIDWORKS? This post covers how to import parts from SOLIDWORKS into 3DEXPERIENCE. Moving forward, we will assume the design is complete and ready to be imported to 3DEXPERIENCE for Simulation (i.e., no further work in SOLIDWORKS is needed).


Fatigue studies simulate the life and damage of a part or assembly due to repeated loading. SOLIDWORKS Simulation has a powerful tool called Variable Amplitude Time History Fatigue that simulates the damage due to loads of, you guessed it, variable amplitude. These studies can help to understand the expected lifetime of a design using realistic variable loads.  


Have you ever cooked a hot dog and then burned your mouth because you couldn't wait? I have, and I then wondered, "what is the best way to orient a hot dog so it cools down the fastest?" National Hot Dog Day is July 20th, so we might as well find the solution. The best method depends on your situation. This post shows how SOLIDWORKS Flow Simulation is a viable solution to manage heat transfer between a solid body and a fluid. 

When performing a Variable Amplitude Time History Fatigue Study in SOLIDWORKS Simulation, a user can view a Rainflow Matrix. What this matrix is and how it’s made may be a question you need to answer. If that is the case, look no further. Rainflow counting is used when performing Variable Amplitude Fatigue studies. In essence, Rainflow counting takes the raw load data and converts it to an equivalent set of constant amplitude stress reversals. 

If you are considering a problem involving thermal analysis, SOLIDWORKS has two tools that you can use. SOLIDWORKS Simulation (FEA software) and SOLIDWORKS Flow Simulation (CFD software) are both capable of solving heat transfer and thermal analysis problems. Both CFD and FEA can perform analysis for all modes of heat transfer. That is conduction, convection, and radiation.
