SOLIDWORKS Simulation: Boundary Conditions and Linear Thermal Expansion (Part 1)

EmailFacebookLinkedInTwitterShare

I’m sure you’ve heard the saying “garbage in, garbage out”.  This applies to lots of things we encounter in life, including our analysis work.  What if you didn’t realize your input was faulty until you review your analysis results and find garbage out?  Would you be able to backtrack your steps and find where you made a mistake?  What if it wasn’t really a mistake, but a misunderstanding as to how a specific tool operates?  I’m going to show you […]

Combining Flow Simulation and SOLIDWORKS Simulation Premium – The Duckbill Valve

EmailFacebookLinkedInTwitterShare

I am always looking for new and exciting ways to combine our great products to make something even better. In my line of work, one of the best combos is the unique marriage between the powerful FEA capabilities of SOLIDWORKS Simulation and the great CFD performance of SOLIDWORKS Flow Simulation. Together they allow a one-way CFD to FEA fluid-solid-interaction (or FSI). But does it stop there? I found a great example the other day that sparked my interest; the duckbill […]

SOLIDWORKS Simulation: Calculating Convection and Verifying Thermal Results

EmailFacebookLinkedInTwitterShare

I have been asked a few times about calculating and applying a convection boundary condition for SOLIDWORKS Simulation Thermal analyses, because without a CFD software, like SOLIDWORKS Flow Simulation, convection must be calculated by hand. As you may already know, there are three modes of heat transfer; conduction, convection, and radiation. SOLIDWORKS Simulation will calculate conduction, but it is up to us to define the parameters for convection and radiation. In this blog I will calculate the convection coefficient of […]

Understanding Mass Participation Factor Results in Frequency Studies

EmailFacebookLinkedInTwitterShare

When conducting a frequency or linear dynamics study in SOLIDWORKS Simulation, a highly recommended, best-practice post processing technique is to investigate both the Effective Mass Participation Factor (EMPF) and the Cumulative Effective Mass Participation Factor (CEMPF) of the output mode shapes. This recommendation was duly noted by my colleague Bill Reuss, in his Blog article from August 27, 2019 entitled ‘Recommendations to Achieve Accurate Results with Linear Dynamic Analysis’. SOLIDWORKS Simulation help defines EMPF as follows: “The effective mass participation […]

Simulia’s SSE changes to SPE. So, What’s in a Name?

EmailFacebookLinkedInTwitterShare

Mid-2018 Dassault Systems and SOLIDWORKS launched a joint project that offers advanced Nonlinear capabilities powered by Simulia, to the SOLIDWORKS Simulation community. Simulia’s Structural Stress Engineer, SSE for short, picks up high strain applications where SOLIDWORKS Simulation Premium stops. The SOLIDWORKS Simulation tool set has been a standard in the FEA world since the late 1980’s Formerly called COSMOS, SOLIDWORKS Simulation Premium has advanced Nonlinear capabilities that help solve advanced engineering problems including geometric nonlinearities, nonlinear materials, and transient problems.

SOLIDWORKS Simulation Setup Tips – A Few Favorites

EmailFacebookLinkedInTwitterShare

Everybody loves shortcuts, right? Who doesn’t like to save time and energy? Setup of SOLIDWORKS Simulation studies is no exception, so I’ll show some of my favorite time saving tips in the analysis of my small garden cart. You may notice that most of these tips are really just SOLIDWORKS CAD functions applied to Simulation, which shows just how well Simulation is integrated into the SOLIDWORKS interface! Hide Excluded Bodies: Simulation has its own set of options. Open the Options […]

SOLIDWORKS 2020 What’s New – Geometry-Based Boundary Conditions

EmailFacebookLinkedInTwitterShare

What do you get when you take something that was good and make it even better?  In this case, you get SOLIDWORKS Plastics 2020!  A year ago, SOLIDWORKS Plastics first introduced Geometry Based Boundary Conditions for injection locations, control valves, and mold wall temperatures.  This began to shift dependency away from the SOLIDWORKS Plastics mesh towards the CAD model geometry.  For those of you familiar with SOLIDWORKS Simulation and SOLIDWORKS Flow Simulation, this is the same mode of operation as […]

SOLIDWORKS 2020 What’s New – Simulation Evaluator

EmailFacebookLinkedInTwitterShare

A brand new feature introduced with the launch of SOLIDWORKS 2020 is a diagnostic tool called Simulation Evaluator. The purpose of this tool is to check the setup of a simulation study, prior to solving, to determine if the setup is correct for a successful simulation. Simulation Evaluator performs a number of system checks prior to running the study which aids the user in the successful setup of the study. It first checks conditions related to the results folder, including the storage […]

SOLIDWORKS 2020 What’s New – Plastics Material Updates Summary and 3D Content Central

EmailFacebookLinkedInTwitterShare

There are several exciting changes to the SOLIDWORKS Plastics program for the 2020 release that will increase ease of use. A couple that I want to highlight are related to the database of polymer materials. First, a couple of vendors, specifically Chevron Phillips and RadiciGroup, have added 29 materials to the installed database. These are shown below. Also, 13 obsolete material grades from EMS-Grivory have been removed from the database. Second, 3D Content Central now has a library of polymer […]

SOLIDWORKS 2020 What’s New – Thermal Loads for Beam Elements

EmailFacebookLinkedInTwitterShare

In SOLIDWORKS Simulation, beam elements are quite common. They offer robust results on long, slender structural members without the compromising solve times that would be required with solid or shell type elements. However, beams have always had a major drawback; they cannot take thermal loads. This was a severe limitation, as many types of structures made from beams may be required to endure large temperature variations. This has been remedied in SOLIDWORKS Simulation 2020 with the addition of Thermal Loads […]
