SOLIDWORKS 2021 What’s New – SW Plastics Enhanced Modeling of Sketch-Based Runners

EmailFacebookLinkedInTwitterShare

As noted in the many blogs you’ve likely seen in the CATI What’s New series, SOLIDWORKS Plastics has been significantly enhanced in the 2021 release. Check out the two key enhancements to the sketch-based runner design that will contribute to more accuracy in your injection molding simulations! The SOLIDWORKS modeling APIs are now used by the algorithm, resulting in more realistic shapes of the runner cross-sections and junctions. An enhanced meshing scheme applies tetrahedral elements at the runner core and […]

SOLIDWORKS 2021 What’s New – Simulation Solver Enhancements

EmailFacebookLinkedInTwitterShare

Have you ever wondered how the characters in those sci-fi movies come up with technical calculations so quickly in their head to save the lives of all when in a serious life-or-death situation? “We’ve got just enough fuel to safely reach Planet Xterron if we keep our speed under warp 9.5. We’ll be only 0.0725 light years ahead of the enemy, but out of range of their photon ray guns!” I’d be in a severe panic, misplace more than just […]

Let’s Go Bowling with SOLIDWORKS Motion – Visualize Pro Render

EmailFacebookLinkedInTwitterShare

In my previous blog on this topic I showed how to use SOLIDWORKS Motion in a virtual simulation to bowl a “Brooklyn Strike.” The simulation presented there was rendered with PhotoView 360. With the introduction of the Visualize program in the SW2016 release we have an alternate way to produce realistic photo renderings of SOLIDWORKS geometry. With Visualize Professional we can export the results of SOLIDWORKS Motion studies directly from SOLIDWORKS. This makes it super easy to bring my Brooklyn […]

SOLIDWORKS Simulation: Result Plot Tips – Part 2

EmailFacebookLinkedInTwitterShare

In a previous CATI blog accessible here, several tips were presented related to post-processing SOLIDWORKS Simulation results. It featured stress plots on mixed mesh models, showed how to present results on selected entities, and highlighted the Stress Hot Spot Diagnostics tool to locate stress singularities. Here I will mention others that I use nearly every time I conduct an analysis. Controlling plot display via the color bar The image below shows the items that are available via right mouse button […]

Particle Separation using SOLIDWORKS Flow Simulation

Particle separators are important devices used to clean industrial process air. One such device that uses inertial and gravitational forces as the separation mechanism is shown in simplified form below. The top view shows that the inlet introduces the flow in a direction that is tangent to the separator wall. In principle, as the flow is introduced, the inertia of the entrained particles makes them collect near the separator walls. Clean air collects in a vortex near the center of […]

3D Hydraulic Jump in SOLIDWORKS Flow Simulation

In my previous blog, I showed an application of the free surface feature in SOLIDWORKS Flow Simulation. For a 2D section of a spillway and flow over a weir, I showed how this feature can accurately predict the hydraulic jump. Well, 2D isn’t that exciting, is it? That’s why we love to use SOLIDWORKS in the first place! So I generated a 3D simulation and found impressive looking results while learning some new things along the way. Here’s the model […]

SOLIDWORKS Simulation: Linking Evaluator Results to Studies

EmailFacebookLinkedInTwitterShare

The 2020 release of SOLIDWORKS Simulation includes a new utility for study management. In a prior CATI blog, my colleague, Alon Finkelstein, introduced the Simulation Evaluator, which checks a study’s setup to determine if it will allow a successful simulation. He gave a great description of how the Evaluator verifies the results folder and material assignments and does a comparison of mesh/solid model volumes to ensure accuracy. I wondered about the usefulness of the “Results” section, and if I would […]

SOLIDWORKS Flow Simulation: Hydrology Applications

EmailFacebookLinkedInTwitterShare

With the addition of the free surface capability, SOLIDWORKS Flow Simulation can now perform simulations of more real-world applications. One commonly encountered Civil Engineering application in open-channel flow design is an energy-dissipation phenomenon called hydraulic jump, which occurs when a fast-moving, shallow flow encounters a relatively slow-moving, deep flow field. Fluid Mechanics texts classify open-channel flow using the dimensionless Froude number (Fr), which is a function of the fluid velocity (V) and depth (y) (ref. F. M White, Fluid Mechanics). […]
