Fixing Mesh Singularities In FEA

Fixing Mesh Singularities In FEA

SOLIDWORKS Simulation has two main ways of mapping a Finite Element mesh onto your CAD geometry – the “Standard” mesher and the “Curvature Based” mesher. In training classes and in prior CAPUniversity webinars and presentations, I’ve always advised that the Curvature mesher is best for single parts, especially parts with thin walls and lots of fillets and rounds […]

Fasteners in FEA Dynamics Simulation

Fasteners in FEA Dynamics Simulation

How best to simulate the dynamics response of a structure with a large number of screws or bolted connections? It is often prohibitively expensive to represent all the hardware, and at the highest level of fidelity, both in terms of set-up time, and also for the computational time. This article lays out a strategy for […]

Rotating Elements In SOLIDWORKS Flow Simulation 2016

With the release of SOLIDWORKS 2016, you can simulate fluid flow around rotating bodies with much higher accuracy. In fact, this is the first time that Flow Simulation has been able to handle an instance of a “Moving Mesh” problem. Prior versions of the Flow Simulation could simulate propellers or turbine blades, but they did […]

User Interface Colors in SOLIDWORKS 2016

User Interface Colors in SOLIDWORKS 2016

I’m a big fan of almost ALL of the improvements in the new SOLIDWORKS 2016. But honestly, I’m not loving the whitewashed look of the Command Icons and the Feature Manager. To be sure, there is a lot of positive spin about how this ‘focuses our attention on the model, not the interface’, and how […]

Rotation-Only Restraints: Locking Out Spin in Simulation

Rotation-Only Restraints: Locking Out Spin in Simulation

How to Restrain Against Rotation(s) in your Solid Model FEA Study We’ve had several CAPUniversity blog articles and KAP’s Corner discussions about how to properly model Simulation studies that undergo large-scale Rotation. But sometimes you need to specify a system of FEA fixtures to prevent rotation, and although accomplishing this is easy, it is not obvious. […]

Tips for Managing Time-Dependent Thermal Analysis

Tips for Managing Time-Dependent Thermal Analysis

If you want to do a time-dependent FEA analysis, you generally need the nonlinear solvers that are available in SOLIDWORKS Simulation Premium. The notable exception to this is the thermal study. This solver, available in Simulation Professional, treats both steady-state and time-dependent problems. In this post I’d like to get into a few of the […]

SOLIDWORKS Simulation: Will It Bond?

SOLIDWORKS Simulation: Will It Bond?

From 2008 to the current version, SOLIDWORKS Simulation has seen a steady march of progress in the ability to bond shell elements to each other, and to the faces of solids. If two shells are built abutting on a common edge, or forming a three-way T-intersection, or overlap with coincident faces, they will bond, and […]

SOLIDWORKS User Interface: Selecting and Removing Color from Faces

SOLIDWORKS User Interface: Selecting and Removing Color from Faces

Here’s a complaint that is more common when working with someone else’s data – How to find/select/remove color schemes that are applied to the model faces? This could arise if you have a native SOLIDWORKS file, but the prior collaborator had a particularly garish sense of style. But more commonly, when you import STEP data […]

SOLIDWORKS Simulation: Large Rotations – Why Do My Parts Swell Up As They Spin?

SOLIDWORKS Simulation: Large Rotations – Why Do My Parts Swell Up As They Spin?

Back in July we ran an hour-long CAPUniversity webinar on the topic of Simulation involving large deflections. A subset of that presentation elicited so much feedback that I decided to elaborate on it as a blog post, to be a more permanent reference and so reach a larger number of users. If you’ve had a […]

SOLIDWORKS Simulation Wicked Fast Study Variations

SOLIDWORKS Simulation Wicked Fast Study Variations

This week’s CAPINC Blog Post is for every SOLIDWORKS Simulation user out there, regardless of what level of license you have. I want to share two tips with you about running studies that require many load-case permutations. One of these tips is very old, one of them is very new, and there is solid gold to […]
