SOLIDWORKS 2019 What’s New – PLASTICS – #SW2019

EmailFacebookGoogle+LinkedInTwitterShare

I’d like to begin by addressing expectation. This blog is intended to explain the enhancements made to SOLIDWORKS Plastics 2019. The actual features may contain some explanation but will not provide all the necessary explanation. For a more complete understanding of SOLIDWORKS Plastics, please consider taking one of our training courses. Our schedule can be found here: https://www.cati.com/solidworks-training/schedule/. In the past, boundary conditions could only be added to the meshed geometry of a part in SOLIDWORKS Plastics. For the 2019 […]

SOLIDWORKS 2019 What’s New – Topology Study – #SW2019

EmailFacebookGoogle+LinkedInTwitterShare

SOLIDWORKS 2019 enhanced Topology studies will include new options for design constraints, export of an optimized shape, and an option to save intermediate results.         … Oh, you’re still here? Well then, lets take this opportunity to look at these enhancements in more depth. Upon browsing through the Topology studies Goals and Constraints feature you will notice 2 new sections; Frequency Constraint and Stress/Factor of Safety Constraint (see below). The Frequency Constraint allows the user to constrain the […]

SOLIDWORKS Simulation: Result Plot Tips

EmailFacebookGoogle+LinkedInTwitterShare

The SOLIDWORKS simulation solved successfully! It must’ve been setup correctly or else it would’ve given an error and, even better, my max stress is below yield! Next problem, please. Pump the brakes! Neither of the statements you just read are indicators of a successful stress study. When the study solves our job, as analysts, this is just beginning. We must analyze the results plots to confirm that the stresses we see are real and not stress singularities and we must […]

SOLIDWORKS Flow Simulation: Lid creation for non-planar faces

What are lids and why do we need them? SOLIDWORKS Flow Simulation supports two main study types, internal (flows bounded by outer solid surfaces, e.g. tanks, office space, etc.) and external (not bounded by outer solid surfaces, e.g. flow over a wing). Internal flow studies often contain geometry that have inlets and outlets. Flow Simulation requires that these inlets and outlets be bounded by a face. These bounded faces will then contain the info necessary to describe the flow for […]

SOLIDWORKS Simulation Case Study: Stress concentrations occurring in places they shouldn’t or too high?

Finite Element Analysis (FEA) results are dependent on model, material, and boundary conditions. However, the boundary conditions have the greatest effect on the results. The boundary conditions in SOLIDWORKS Simulation must reflect the conditions in the physical experiment. A good example is the scissor lift shown below (Figure 1). As we all know, scissor lifts are designed with legs that are collapse and expand. These “legs” are pinned together. If a load is placed on the lift, then the whole structure […]

SIMULATION: Resolve Contact Set for Bodies That Overlap

Have you ever seen bodies pass through each other in SOLIDWORKS Simulation? You cannot always easily observe overlapping behavior. This depends on if deformed result display is used and, if so, which deformation scale is selected. In the example below I created a multi-body part, fixed the 2 rectangular parts in place, and added a horizontal load at the end of the L-shaped part. I bonded the smaller rectangle body which acts as the support for the L-shaped body. To […]

SOLIDWORKS Simulation: Which Solver should I use?

EmailFacebookGoogle+LinkedInTwitterShare

SOLIDWORKS Simulation provides users with several options when selecting a solver, they include: Direct Sparse, Intel Direct Sparse, Large Problem Direct Sparse, Intel Network Sparse, and FFEPlus. With all these options how does a user know which one is correct for their simulation study? Fortunately, SOLIDWORKS has a procedure to automatically select solvers. Automatic Solver Selection SOLIDWORKS uses the FFEPlus iterative solver by default unless certain conditions are present. Under these “certain conditions” the Direct Sparse solver will be chosen […]

Stratasys Connex 3D Printers Who is Stratasys? Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota. Crump thought of creating shapes layer by layer and of a way to automate the process. In April 1992, Stratasys sold its first product, the 3D Modeler. Crump patented fused deposition modeling (FDM) technology and in 2003, FDM was the best-selling rapid prototyping technology. On April 16, 2012, Stratasys announced that it agreed to merge with privately held Objet Ltd., a leading manufacturer of 3D […]

SOLIDWORKS Static Simulation Highlights

EmailFacebookGoogle+LinkedInTwitterShare

Who uses Static Simulation? SOLIDWORKS linear static stress analysis enables designers and engineers the power to validate their design quickly and efficiently. Validation is done within the SOLIDWORKS application utilizing a familiar user interface and eliminating the need to export data to another software package. Linear stress analysis no longer must be delegated as a post design process. The validation and design become a simultaneous process instead of sequential. What is Static Simulation? SOLIDWORKS Simulation uses finite element analysis (FEA) methods to determine the […]

SOLIDWORKS 2018 What’s New – Flow Simulation Noise Prediction – #SW2018

EmailFacebookGoogle+LinkedInTwitterShare

SOLIDWORKS 2018 What’s New – Flow Simulation Noise Prediction – #SW2018 For many engineer’s noise intensity due to flow turbulence is a critical design criterion. Designers must consider noise output from industries as diverse as kitchen appliances, automotive, and defense. Unfortunately, not until recently, users could only interpolate a general sense of noise output by viewing turbulence plots. Now, in SOLIDWORKS 2018, Flow simulation has new capabilities to show acoustic plots. The image below utilizes decibel (dB) units to display acoustic […]
