“Under the hood” of SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

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 […]

“Under the hood” of SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

The field of Computation Fluid Dynamics (CFD) is a sophisticated engineering discipline based on the Reynolds Averaged Navier-Stokes (RANS) equations that govern fluid flow, heat and mass transfer. CFD has a reputation for being extremely complicated and has typically been the domain of specialists, physicists and academics, using super computers. Typically, the quality of CFD results is greatly affected by the quality of the mesh and the attentiveness of the user to the pre-processing stage. Consequently, traditional CFD software codes […]

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: Remote Solver Setup

EmailFacebookLinkedInTwitterShare

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 […]

Hot Air Goes Up, Right? Confirmed With SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

Warm air rises, and Cold air descends. This is a simple concept that we learned early on in life. We can feel it if we place our hand above a hot stove, or notice our basement is always the coldest part of the house. But why does this happen, and what does this have to do with SOLIDWORKS Flow Simulation? Warm air rises and cold air sinks due to gravity. Yes, gravity the invisible force that holds all of us […]

SOLIDWORKS Flow Simulation Verification. Verified!

Verification that the software you use is doing what it is supposed to do is nothing new. We just may not know how to access this information. Like my colleague Kurt Kurtin who discussed the SOLIDWORKS Simulation Verification documents in his blog Simulation Verification – How Accurate are My Results, I wanted to make sure you knew where these verification documents are located for SOLIDWORKS Flow Simulation. The Flow Simulation verification documents are a little more hidden than the one […]

Softening Butter with SOLIDWORKS Flow Simulation.

EmailFacebookLinkedInTwitterShare

When it comes to the Warren household, cookies are the dessert of choice (mine anyway), specifically Snickerdoodles. Nothing compares to the soft and buttery, cinnamon-sugar coated discs of deliciousness. I make these from scratch, and usually on a whim. This leaves me with one problem every time I make the cookies; the cold hard butter. I always forget to take the butter out of the fridge and give it time to soften. Then I must wait even longer to enjoy […]

Now that SOLIDWORKS 2018 has been released for a few months, I’ve had the opportunity to look through many of the new features. My primary interests are the new features and functionality included in the Simulation suite of products. When our Technical Team was writing about many of the new features in 2018, more than a few piqued my interest. One specific enhancement for SOLIDWORKS Flow Simulation really piqued my interest to investigate further. I found an interesting model to […]
