Simulation Verification – How Accurate are My Results?

EmailFacebookLinkedInTwitterShare

Do you need to provide documentation about the accuracy of the Simulation program to support a Quality Assurance (QA) process in your company? Or have you ever asked yourself; “How do I know I’m getting accurate results?” No need to guess or worry, the SOLIDWORKS Simulation team has provided verification problems with comparison to theory to support this need. To access the full list of these problems and open the model files associated with each, navigate within SOLIDWORKS to the […]

Design Intent, Not Just for Modeling.

EmailFacebookLinkedInTwitterShare

If you have taken a SOLIDWORKS Essentials course from CATI you will have heard the phrase “Design Intent” at least 100 times. Design Intent is not something to be taken lightly in the modeling world. It allows the user to get the most out of their parametric model. So, what is Design Intent? Design Intent is how the model should behave when changed. The way in which the model is created governs how it can change. Automatic sketch relations, equations, […]

SOLIDWORKS Simulation: Draft Quality and High Quality Elements – Part 2

EmailFacebookLinkedInTwitterShare

Have you ever proofread your own writing a dozen times and not recognized a mistake?  Well, in Part 1 of this blog I did just that.  It must have been the lucky number 13 re-read to realize my blunder!  My original premise was to use the same number of nodes along any edge in the finite element model.  So, when I referenced Part 1’s ‘Figure 5‘ and wrote: “The difference in results between 3 high quality elements and 4 draft […]

Softening Butter with SOLIDWORKS Flow Simulation.

When it comes to the Warren household, cookies are the dessert of choice (mine anyway), specifically Snickerdoodles. Nothing compares to the soft and buttery, cinnamon-sugar coated discs of deliciousness. I make these from scratch, and usually on a whim. This leaves me with one problem every time I make the cookies; the cold hard butter. I always forget to take the butter out of the fridge and give it time to soften. Then I must wait even longer to enjoy […]

SOLIDWORKS Simulation: Draft Quality and High Quality Elements – Part 1

EmailFacebookLinkedInTwitterShare

It’s all about the nodes and the equations!   At least that’s what my office mate, Chris, says. I’m not going to disagree with him, rather I am going to show that he is correct.  That statement arose while discussing meshing in SOLIDWORKS Simulation and getting reasonably accurate results with Finite Element Analysis.  That leads to the simple question “can I achieve accurate results using a draft quality mesh”? In SOLIDWORKS Simulation, the easiest method of differentiating between a draft quality […]

SOLIDWORKS Flow Simulation: Joule Heating

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Flow simulation is a fantastic tool for simulating internal or external fluid flows. It also features very robust conjugate heat transfer capabilities; including conduction, convection, and radiation. The combination of these capabilities has made SOLIDWORKS Flow Simulation the go-to program to simulate cooling electronic components. It does this fantastically right out of the box, but with the addition of the Electronics Cooling Module, it gets even better! Today I’d like to cover one of the flagship capabilities of the […]

SOLIDWORKS Simulation: Reaction Moment Using Solid Element

EmailFacebookLinkedInTwitterShare

When running an FEA on an assembly or large part the first thing we normally do is reduce the complexity of the geometry so that the calculation times remain short. At times this would mean that we would get rid of the main structure and only calculate the reaction forces and moments on a subassembly or smaller region of a part. While doing this we may end up using tetrahedron elements, or solid elements, to mesh our geometry. Solid elements […]

SOLIDWORKS Simulation: Causes of Incremental Strain Error

EmailFacebookLinkedInTwitterShare

This problem comes in during the calculation of two consecutive time steps in a nonlinear analysis. If the material deforms drastically without some proportional stress increase, then the software will stop the calculation and throw up an error message. The message may read something along the lines of “Incremental plastic strain is too large”. The solution may not be straightforward as to turning on an option. When you’re working with metals or non-rubber like materials, you should dig into the model […]

Bonded, Bolted, or Pinned – Why You Should Simplify Your Analysis

EmailFacebookLinkedInTwitterShare

Simplify, simplify, simplify!  I cannot count how many times I’ve had this discussion with customers when reviewing their CAD models and listening to what they want to analyze with SOLIDWORKS Simulation.  I know how easy it is to start a new SOLIDWORKS Simulation study and begin setting up an analysis on fully-featured CAD models – click a button and you’re on your way.  Let’s look at an example of starting simple and working towards the complex with SOLIDWORKS Simulation that […]
