SOLIDWORKS 2022 What’s New – Plastics Injection Location Advisor

EmailFacebookLinkedInTwitterShare

Included with SOLIDWORKS Plastics 2022 is a tool called “Injection Location Advisor” that makes it easier to optimally position injection locations for plastic parts. The tool can be found in the PlasticsManager tree, under boundary conditions. The property manager looks like this when opened: You can adjust the number of injection locations (up to a maximum of 4) and the mold open direction. The software will automatically detect a plane for the mold open direction (in this case the top […]

Calculating critical shaft speeds in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

It is essential to understand the critical speed of rotating machinery to ensure safe and reliable operation of the equipment. Critical shaft speed is the speed at which a shaft becomes resonant. At this speed, vibration can cause the machinery to function incorrectly and cause issues such as loosening of parts, poor vibration characteristics and even bearing and foundation damage. Unexpected downtime because of a mechanical issue can cost a company thousands of dollars in lost productivity. Critical speed occurs when […]

Understanding beam diagrams in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

When conducting a finite element analysis (FEA) of a weldment structure in SOLIDWORKS Simulation, the software will default to meshing each structural member using beam elements. Beam elements are one dimensional finite elements, where the section properties of the beam (inertia, cross sectional area, torsion constant, etc.) are accounted for in the mathematical model as opposed to the geometrical model. In other words, when we use beam elements to mesh an extruded shape, we don’t subdivide the cross section of […]

Importing a custom material into SOLIDWORKS Plastics

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Plastics comes preloaded with an extensive library of plastic materials to use in your plastic simulation studies. The vast database includes thousands of unique materials, grouped into 133 resin families. Alternatively, they can be sorted by the 196 different manufacturers that provided their plastics material data to SOLIDWORKS Plastics. For most simulations, assigning a plastic resin to the model is a simple matter of searching the database, choosing your material, and applying it to your injection molded part. However, […]

Tips and Tricks for Post Processing in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Simulation makes the process of setting up, solving and post-processing a simulation study easy and intuitive. In this blog I will share some of my favorite tips and tricks for the post processing stage. Tip #1: Start post processing with displacements not stresses When the SOLIDWORKS Simulation solver is complete, the results are automatically loaded into the results folder. Typically, the results folder will include default plots of von Mises stress, displacement and strain (in that order) and after […]

What Can I Learn in a Buckling Study?

Like most of the central United States, the Chicago area (where I live) experienced a brutal February 2021 with frigid temperatures and lots of snow. We got whacked with a serious blizzard that lasted about 36 hours. This was the scene outside my back door when the blizzard was over. That’s 22 inches of fresh powder on my patio table. After the backbreaking work of shoveling the driveway was complete, I started to wonder whether my patio table was in […]

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 […]

Fastener Functionality in SimSolid

EmailFacebookLinkedInTwitterShare

SimSolid by Altair is comprehensive, fast, accurate and easy-to-use software that can perform advanced structural analyses on complex, fully featured CAD assemblies within minutes. SimSolid eliminates geometry preparation and meshing: the two most time-consuming, expertise-extensive and error-prone tasks performed in a conventional structural simulation. A great example of this functionality is how fasteners are handled in SimSolid. As part of the preprocessing phase, most other FEA programs require simplification of the CAD model before the study can be solved. Regarding […]

SOLIDWORKS 2021 What’s New – Meshing Enhancements

EmailFacebookLinkedInTwitterShare

SOLIDWORKS 2021 includes several improvements to the meshing algorithms and workflows. These meshing improvements fall into three categories; faster meshing algorithms, improved default options and enhanced capabilities to rapidly resolve any mesh failures. Improved options for default mesh settings Default options in SOLIDWORKS Simulation are automatically applied to new studies. A common use of default options is to set-up standardized result plots that always display in the results folder once a study has finished solving. We can also use default […]
