Slow Your Roll, Slow Rotating Regions in SOLIDWORKS Flow Simulation.

If you have used SOLIDWORKS Flow Simulation, you will likely know that one of the best enhancements in recent years is the “Sliding Mesh” rotating region feature. This boundary condition is geared towards turbo machinery design, allowing the impeller/ rotating geometry to drive fluid flow. This technology is an advanced option for designing impellers, volutes, propellers or anything else you want to rotate in a fluid. As you might have noticed these applications rotate at a fast rate usually 100’s […]

Modeling fans in SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

There are a few ways to model fans or impellers in SOLIDWORKS Flow Simulation. The most accurate method involves modeling the actual fan/impeller blades and solving the study as a sliding mesh (rotating reference frame) problem. In this type of analysis, the mesh moves from one time-step to the next. This is a transient analysis and consumes a considerable amount of computational resource, typically resulting in exceedingly long solution times. This type of analysis is recommended for fan manufacturers who […]

How do I view SOLIDWORKS Flow Simulation Results and Create My First Cut Plot? SOLIDWORKS Flow Simulation is a computational fluid dynamics (CFD) analysis software. Flow Simulation provides an understanding of fluid motion around or through your design. For an understanding of how to create and solve a Flow Simulation study please see the accompanying blog “How do I create a Flow Simulation analysis project?”. Once your study is created and run the next step is to interrogate the results. […]

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 […]

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 […]
