“Under the hood” of SOLIDWORKS Flow Simulation

In Part 1 of this two-part blog I highlighted some of the main characteristics of SmartCells, the unique technology found ‘under the hood’ of SOLDWORKS Flow Simulation that provides for speed, accuracy and ease-of-use of the software. To recap, the five most important features are: SmartCells are Cartesian based meshes that are typically an order of magnitude smaller in size (i.e. cell count) than traditional CFD meshes while still providing the same level of resolution and accuracy SmartCells handle complex […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study (Part 2)

EmailFacebookLinkedInTwitterShare

In part 1 of this Blog article I investigated the drag characteristics of the Tesla Cybertruck and explored how symmetry boundary conditions can be used to speed up a flow analysis project in SOLIDWORKS Flow Simulation. In part 2, I am going to demonstrate some of the nuances for correctly setting up a “Virtual Wind Tunnel” in SOLIDWORKS Flow Simulation. Before the widespread adoption of Computational Fluid Dynamics (CFD), engineers who sought to explore the aerodynamics of different vehicle shapes […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study

When Tesla launched their Cybertruck pickup model in November, I was intrigued by its unique shape. Given the very angular, wedge-like styling, the first thought that came to mind was that I could have designed the exterior shape in SOLIDWORKS in 5 minutes with a few extrudes, cuts and draft features. I have no doubt that I could have saved Tesla millions of dollars spent on their exterior stylists and designers! I also pondered whether this shape performed well aerodynamically […]

SOLIDWORKS Flow Simulation: Calculation of Hydrostatic Pressure

If you are an experienced SOLIDWORKS Flow Simulation user, chances are you’ve turned on the “Gravity” setting to account for buoyancy effects that exist when a fluid’s density changes with temperature. This is a very commonly used feature of the program. Buoyancy is an amazing physics principle that allowed the Montgolfier brothers to make the historic first “lighter than air” flight in Paris in 1783. One thing you may not be aware of is that when the gravity feature is […]

SOLIDWORKS Flow Simulation: Remote Solver Setup

Think about the last time you needed to solve a very large SOLIDWORKS Flow Simulation project.  Did your workstation have enough horsepower to solve the project in a reasonable amount of time?  If not, did you have access to a high-end workstation elsewhere in your office that you could have connected to?  If the answers to those questions are ‘no’ and ‘yes’, respectively, then you could have taken advantage of SOLIDWORKS Flow Simulation’s Remote Solver capability.  Utilizing the Remote Solver […]

Flow Simulation: Computational Domain Editing Part 2 – Periodicity

EmailFacebookLinkedInTwitterShare

In Part 1 of this blog series, I covered the SOLIDWORKS Flow Simulation computational domain symmetry condition setting to reduce the size of the computational fluid dynamics (CFD) problem to be solved. The result is a decreased solution time and required computer memory. This blog will show how another computational domain condition, periodicity, can be used in those situations where you have a pattern of identical components in the flow field. I’ll continue to use the Lockheed F-117 Nighthawk stealth […]

How well do you know your Property Managers in SOLIDWORKS, SOLIDWORKS Simulation or SOLIDWORKS Flow Simulation? Do you really pay attention to all the buttons and options that you can use for any specific feature? Chances are, if you’re like me, you looked at all the bells and whistles the first time or two and then quickly forgot about each available option. We tend to learn exactly what we need to know, get good at that, and move on. Which brings […]

SOLIDWORKS Flow Simulation Highlights

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Flow Simulation Highlights SOLIDWORKS Flow Simulation is our full computational fluid dynamics (CFD) Solution that simulates fluid (liquid or gas) flowing through or around objects. It enables quick, efficient simulation of the flow field and includes heat transfer effects. The program is directly integrated within the familiar SOLIDWORKS interface and can communicate with the Simulation finite element analysis (FEA) tool to allow inclusion of pressure and/or temperature effects of fluid flow within thermal/structural FEA simulations. An efficient wizard interface […]

SOLIDWORKS: Flow Simulation Trajectory Plots

EmailFacebookLinkedInTwitterShare

Flow Simulation Trajectory Plots   Trajectory plots in SOLIDWORKS Flow Simulation can be very informative for flow visualization; however, it is sometimes tricky to get what you want when using them with external flow results. I’ve found that for the starting point reference, sketches with patterned lines will generate a nice set of trajectories. Also, using planes that are parallel to the dominant flow direction can be useful. This reference selection choice is counter-intuitive but produces surprisingly good results.   […]

Flow Simulation 2017 Transient Explorer

How often do you solve transient problems in Flow Simulation?  For a good portion of our users, nearly every computational fluid dynamics problem they solve is time dependent.  Once the problem has solved, how do you review and visualize the transient results? Until recently there were only two options – review results for a single solved time step or export the transient data to the Animation Wizard.  With the first option, the user would have to load results from a […]
