SOLIDWORKS Simulation: Hand Calculations

EmailFacebookLinkedInTwitterShare

Recently, I was discussing the use of hand calculations in conjunction with Finite Element Analysis (FEA) with one of our customers. His belief is that hand calculations are a waste of time, that they are never accurate enough to represent what he designs. Simply put, how can an equation referencing material properties, geometric characteristics, or section properties needed in many structural analysis calculations represent the complex designs he creates today. That is a strong and fair argument that I cannot […]

A Tropical Fish and SOLIDWORKS Simulation Meshing – What’s a fish got to do with FEA?

A Tropical Fish and SOLIDWORKS Simulation Meshing – What’s a fish got to do with FEA? The Bluehead Fairy Wrasse, a tropical fish native to the western Atlantic Ocean, can be found near coral reefs in schools feeding on small organisms, acting as a cleanup crew for the reef. ( ref. Bluehead Wrasse – Wikipedia). I’ve enlisted the wrasse’s help in describing the importance of good meshing practices in SOLIDWORKS Simulation. As you will see, it’s all about the details […]

Grilling with SOLIDWORKS Simulation Professional – Thermal Study

EmailFacebookLinkedInTwitterShare

We all know it’s way too cold to cook burgers on the outdoor grill this time of year. For some, the grill might even be covered in snow! With the right seasonings, however, pan fried burgers will do just fine. But although I’ve got the timing down using the grill, I’m not sure how long to cook them in a pan to get a medium rare result. SOLIDWORKS Simulation Professional thermal study can help with that. So, grab a skillet, some spices […]

Simulation Premium’s Silver Bullet

Recently I was asked if SOLIDWORKS Simulation could simulate a projectile striking another object.  In this case specifically the projectile was gravel and the object was a vehicle fascia.  I had to think about this for a second.  Usually when an engineer thinks of FEA they think of a linear material, static loading cases, and small displacements.  SOLIDWORKS Simulation Premium shatters these expectations with a silver bullet by offering not only Non-Linear materials, but Transient(dynamic) Large Displacement problems.  Non-Linear Dynamic […]

Simulation 2014 Interface Improvements

EmailFacebookLinkedInTwitterShare

Last month I wrote about Toolbox fasteners with SOLIDWORKS Simulation and how they can be converted automatically to connectors in simulation studies.  Today I’m going to focus on improvements to the Simulation interface for post processing.  One thing that Simulation users can struggle with is selecting the correct option for modifying the plots generated from an analysis.  Even with as many years as I have used SOLIDWORKS Simulation, I occasionally edit the definition of a plot when I meant to […]

Automatic Conversion of Toolbox Fasteners in Simulation 2014

EmailFacebookLinkedInTwitterShare

With each new release there are always a few additions to SOLIDWORKS Simulation that catch my eye.  This year’s 2014 release is no different. I’ll write about several of the enhancements over the coming months but I’m going to start with the conversion of Toolbox fasteners into Simulation connectors. Using connectors in Simulation allows us to replace physical components with virtual ones which will reduce the time required to solve the analysis.  In Simulation 2013 and prior, there are a […]

Parameters and Design Studies

EmailFacebookLinkedInTwitterShare

In my opinion, one of the most underutilized tools in SOLIDWORKS Simulation is the Design Study.  Design studies allow you to easily set up a number of ‘what if’ scenarios and run them all with the click of a button.  Sure, it might take a couple extra minutes to set up a few parameters, but the extra setup time will pay off handsomely later. Let’s take a look at the effects of varying mesh size for a stress concentration.  The […]

Submodeling in Simulation 2013

EmailFacebookLinkedInTwitterShare

Was it really last year that Vik wrote about Two Neat Additions  to Simulation in 2013?  How time flies!  For all its power, the addition of Submodeling studies for Simulation 2013 has seemingly gone unnoticed by our Simulation user base. In most cases, we are usually interested in the performance of a small portion of the model, maybe a part or two of the whole design.  In order to get to that area of interest, we need to analyze a […]

SOLIDWORKS Simulation-Using Symmetry

EmailFacebookLinkedInTwitterShare

Geometric and Loading Symmetry Some geometric shapes possess the property of symmetry. If a body, or an assembly of components, is able to be cut such that mirroring or patterning the remaining portion can be used to represent the entire body, then the body or assembly is said to be symmetric. Symmetry in the loading application is also present if the loading can be cut such that mirroring or patterning of the remaining portion can be used to represent the […]

Solver Selection – Does It Matter?

EmailFacebookLinkedInTwitterShare

Choices. Everyone wants choices. We make simple choices like ‘paper or plastic’. Or one of my favorites, ‘domestic or import’! In SOLIDWORKS we can be faced with decisions like ‘assembly or multi-body’! While these are simple examples, what do you decide when you’re faced with the decision ‘FFEPlus or Direct Sparse’? Which solver should you select? While this question does not have an easy answer, there are some guidelines you can follow to help in your selection. Understanding the two […]
