Harnessing the power of topology studies in SOLIDWORKS Simulation: Part 2

EmailFacebookLinkedInTwitterShare

Topology studies, available in SOLIDWORKS Simulation, are a highly effective way for design engineers to create lightweight, optimized parts. Topology studies can be used to explore a variety of design iterations to satisfy an optimization goal, subject to a set of geometric constraints. Topology studies start with a maximum design space which represents the maximum allowable size for the component. The topology optimization then seeks a new distribution of material, within the boundaries of the maximum allowable geometry, considering all the […]

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 […]

Understanding Mass Participation Factor Results in Frequency Studies

EmailFacebookLinkedInTwitterShare

When conducting a frequency or linear dynamics study in SOLIDWORKS Simulation, a highly recommended, best-practice post processing technique is to investigate both the Effective Mass Participation Factor (EMPF) and the Cumulative Effective Mass Participation Factor (CEMPF) of the output mode shapes. This recommendation was duly noted by my colleague Bill Reuss, in his Blog article from August 27, 2019 entitled ‘Recommendations to Achieve Accurate Results with Linear Dynamic Analysis’. SOLIDWORKS Simulation help defines EMPF as follows: “The effective mass participation […]

SOLIDWORKS 2020 What’s New – Simulation Evaluator

EmailFacebookLinkedInTwitterShare

A brand new feature introduced with the launch of SOLIDWORKS 2020 is a diagnostic tool called Simulation Evaluator. The purpose of this tool is to check the setup of a simulation study, prior to solving, to determine if the setup is correct for a successful simulation. Simulation Evaluator performs a number of system checks prior to running the study which aids the user in the successful setup of the study. It first checks conditions related to the results folder, including the storage […]

SOLIDWORKS 2020 What’s New – Free Body Forces for Nonlinear Studies

EmailFacebookLinkedInTwitterShare

A neat new feature that has been added to SOLIDWORKS 2020 is the ability to interrogate free body forces after running a nonlinear static or nonlinear dynamic study. The ability to compute and interrogate free body forces in SOLIDWORKS as part of simulation post-processing has existed for a long time but has been limited in previous versions of the software to linear static or dynamic studies. The first step in the process is to make sure the button for Compute […]
