Making Sense of Simulation Meshing- Part 2 Welcome to part 2 of the 3 part series about mesh considerations in SOLIDWORKS Simulation. In part 1, we covered some high-level considerations and adaptive meshing. If you missed part 1, view it here. In this post we will discuss some mesh quality tools SOLIDWORKS Simulation has to offer. In the last post we will discuss different types of elements and meshes for Finite Element Analysis (FEA, FEM). Moving on, knowing if your FEA mesh is a good quality is essential to accurate studies using SOLIDWORKS Simulation. Luckily, SOLIDWORKS has supplied us with some great tools for interrogating the mesh too
Making Sense of SOLIDWORKS Simulation Meshing – Part 1 As an Application Engineer specializing in SOLIDWORKS Simulation, I often get asked, “How do I know if I have a good mesh?” The simple answer is, it’s not so simple. This is the first blog in a 3 part series that I will be posting about meshing. In this blog we will discuss meshing considerations for study types and purposes as well as mesh convergence considerations. The next two blogs in the series will talk discuss mesh quality tools, what they mean, and the types of meshers. Meshing is a term for the process of discretizing CAD geometry. For the
Task Scheduler for Simulation Runs By now, must people know the benefit that the “Run All Studies” and “Run Specified Studies” that SOLIDWORKS Simulation provides. These functions are limited in that they only work for a single part/ assembly file with or without different configurations. However, what happens when there is more than one file with multiple studies that need to be solved overnight? To accomplish this, we can turn to the often underused SOLIDWORKS Task Scheduler. Task scheduler allows users to automate a multitude of repetitive tasks including importing/ exporting files, Updating files, printing, rendering, and of course, updating Simulations in SOLIDWORKS. In order to run SOLDIWORKS
Simulation Beam Elements with Non-Planar Bonds Recently I came across an issue bonding beam elements to non-planar faces on a body meshed as solid. It seemed like good information to share. Below is a simplified model of the model that was being simulated using SOLIDWORKS Simulation: The red shaft was being treated as a beam element and loaded axially. The bottom of the shaft was fixed and the outside ring of the green body or “ring” as I will refer to it is fixed as well. The two parts in the assembly are bonded where the outer face of the shaft meets the inner face
Simulation On Thin Objects and Non-Circular Springs Often times we need to be able to know the stresses on thin members such as springs and clips. Making these objects in SOLIDWORKS can be an adventure, but more often than not, simulating them can be just a plain headache. Circular springs are easier to simulate because all of the loading is axial and the spring profile is circular. For this reason, I chose a non-circular spring. Here is an example of a non-circular spring from a piece of machinery that is being compressed 200 mm: First, just a quick lesson on how it was made.
Simulation Results Processing This article is a continuation of the article posted earlier this month regarding the new Stress Hot Spot Feature. The previous article showed how a college student designing their own phone case simulated how the case would act under loading. Below is what the Stress Hot Spot Feature came up with. By setting a maximum value for our stress plot, we can specify the color that we want values above that to be. This is done by clicking the top of the color gradient on our plot key. This feature in SOLIDWORKS 2017 makes for easier communication and results visualization, but
Stress Hot Spot Feature Many people may not be experts in FEA or SOLIDWORKS Simulation. It is a complex topic that requires practice and know how to get realistic results. Fortunately for designers, SOLIDWORKS Simulation results just got a little bit easier to work with. SOLIDWORKS 2017 has released a new feature called Stress Hot Spot Diagnostics. What this tool does is shows and isolates elements that have much higher stress values than adjacent elements. The mathematics of FEA analysis are limited in that when stress is calculated at a sharp corner, the value of stresses at that corner diverge to an infinite value as the mesh gets
