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 […]

SOLIDWORKS: Blended Curvature Based Mesh in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

Blended Curvature Based Mesh in SOLIDWORKS Simulation   Meshing a part appropriately might be tenuous at times, but it is certainly a lot easier in SOLIDWORKS than just about any other software. We don’t want to set the expectation that meshing is a problem for SOLIDWORKS. Getting a good aspect ratio around the smaller geometry can drive you and your computer a bit crazy, especially if you don’t know the smallest size of your geometry. SOLIDWORKS introduced the blended curvature based […]

Simulation tips for Flip Shell Elements

Have you ever worked on a complicated Simulation study with many thin components meshed with shell elements?  If you have, you’re familiar with the face colors for shell elements – silver for the top face, orange for the bottom face.  The face colors provide a visual link from the 2-Dimensional representation of our part back into 3-D space.  At some time, you may have encountered ‘top’ and ‘bottom’ faces in the mesh being adjacent to one another, or a mis-alignment […]

Beam Elements in Simulation

One of the things that we emphasize in our Simulation Training classes is simplifying the model. It’s an easy concept to understand – the simpler the model, the faster you’ll get results! For designs that use SolidWorks’ weldment functionality, Simulation will automatically make one of the most significant idealizations of a model. 3-D geometry is idealized into a 1-D finite element for the mesh, a Beam element. Here is a simple example where two standard c-channel structural members come together […]

Mesh Failure Diagnostics, Part 2

EmailFacebookLinkedInTwitterShare

Last month, I wrote about Mesh Control and described a process using the Simulation Advisor to fix mesh errors.  If you prefer to operate without the proverbial ‘phone-a-friend’ option, you can always turn the Simulation Advisor off by un-checking the box in your Simulation Options, as shown.  When you uncheck this box, you still have the option of accessing the Simulation Advisor from the Command Manager by selecting the appropriate Advisor in the pull-down menu. When an assembly failed to […]

Mesh Control: As Easy as 1-2-3

EmailFacebookLinkedInTwitterShare

When is the last time you saw this warning dialog when meshing?  If your primary responsibilities include FEA, chances are it was as recently as yesterday. As we continue to design and analyze increasingly complex models, our need to access mesh controls will increase proportionally.  Wouldn’t it be nice if accessing those tools were made simple?  Amazingly enough, they already are!  At the conclusion of a failed mesh, just click on the Mesh Failure Diagnostic button. Yes, it is that […]
