SOLIDWORKS 2022 What’s New – SOLIDWORKS SIMULATION – Blended Curvature-Based Mesher

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Simulation 2022, like we have seen in several prior releases, includes updates to the meshing algorithms.  Let’s face it.  When it comes to finite element analysis, “it’s all about the mesh”, as one of my co-workers often chides.  Digging in to new features of SOLIDWORKS Simulation 2022, using the Blended Curvature-Based meshing algorithm, we can now apply a mesh control that has a larger element size than the global mesh settings.  This is an interesting change and, in my […]

Are you ready for SOLIDWORKS Simulation 2022?

EmailFacebookLinkedInTwitterShare

SOLIDWORKS 2022 is coming!  What does that mean for you and me?  Simple.  New features, functionality, User Interface changes, performance improvements, and possibly a whole host of other changes to SOLIDWORKS CAD, but also SOLIDWORKS Simulation, SOLIDWORKS Flow Simulation, and SOLIDWORKS Plastics.  As I write this, I am unfortunately not able to mention what’s coming.  You will find that content in several upcoming blogs written by me and several other of my Simulation colleagues by searching the Computer Aided Technology […]

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 […]

Napkin Sketches, Hand Calculations and… SOLIDWORKS Simulation?

EmailFacebookLinkedInTwitterShare

Why do we Designers and Engineers resort to napkin sketches and hand calculations?  Some people would say it is because we are gluttons for punishment!  Other people might recognize that a napkin sketch is a great way to convey a new idea quickly.  Still others might voice an opinion that hand calculations provide quick insight into performance.  Whatever your reason for resorting to a napkin sketch or hand calculation is, I say keep doing it!  What do either of these […]

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 […]

Mesh Controls in SOLIDWORKS: Not just for Faces and Edges

EmailFacebookLinkedInTwitterShare

When it comes to mesh controls, people often ask if they can be applied to an entire part instead of to edges, faces and vertices. The answer is of course “Yes”, but the method is slightly different than it is for edges, faces, and vertices. Outside of the mesh failure diagnostic window, there are two workflows/methods for applying mesh controls to parts and one of them is a little less obvious than the other. Let’s dive in and start with […]

Give Cyclic Symmetry a Spin in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

If I told you that it was possible to make your analysis solve faster, would you be interested?  You absolutely should be!  Faster solve times allow you to analyze more iterations and make better informed decisions to improve your designs.  Today I am going to explain how to use another method of reducing your finite element model using Cyclic Symmetry in SOLIDWORKS Simulation. Hopefully you are familiar with using a symmetry boundary condition in SOLIDWORKS Simulation.  Symmetry allows you to […]

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

EmailFacebookLinkedInTwitterShare

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 […]

Insert Molding with SOLIDWORKS Plastics

EmailFacebookLinkedInTwitterShare

What is the correct term – insert molding or insert overmolding?  I hear the terms used almost interchangeably in conversations about SOLIDWORKS Plastics.  I always ask the speaker for clarification.  The ask is not because I do not understand what both terms mean, I want to make sure that we are discussing the same thing.  Let’s clarify the terms so we can move forward with today’s blog.  Insert molding is the process of adding an insert, typically a metal component, […]

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 […]
