SOLIDWORKS Simulation: Boundary Conditions and Linear Thermal Expansion (Part 2)

EmailFacebookLinkedInTwitterShare

In Part 1 of this SOLIDWORKS Simulation blog, I demonstrated how improper boundary conditions led to incorrect analysis results with Linear Thermal Expansion – “garbage in, garbage out”.  Now let’s look at what was happening under the hood with my analysis when applying temperature boundary conditions to a linear static study. Recall that I initially identified an issue with my results when reviewing the resultant displacement plot (Figure 6 in the Part 1 blog).  I’m going to use a Thermal […]

Generative Design Meets Additive Manufacturing

EmailFacebookLinkedInTwitterShare

Certain things in this world go together. Peanut butter and chocolate, pinball machines and arcades, and Jeeps and off-road. Generative Design and Additive Manufacturing are part of the great pairing’s hall of fame. We all know what Additive Manufacturing or, 3D Printing is. 3D Printing has become a household word over the last decade. 3D Printing creates something from nothing, layer after layer to print your part. Generative design, or Topology Optimization, is like 3D Printing; building the design before […]

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 […]

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 […]

 SOLIDWORKS 2020 Installation Guide Part4 – Composer, Plastics, Inspection, MBD and Simulation Installation 

EmailFacebookLinkedInTwitterShare

What do I need to know to install my Composer, Plastics, Inspection, MBD, or Simulation package? First, all these products are installed thru the SOLIDWORKS installation manager. To download the installation manager, you will need to click the SOLIDWORKS download link. Run the installation manager and enter the serial number for your products. If you have all your licenses set up to be renewed at the same time you may have only one SOLIDWORKS serial number for all your assets. […]

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 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 – Selecting a SOLIDWORKS Simulation License with SolidNetWork License

EmailFacebookLinkedInTwitterShare

When it comes to SOLIDWORKS Simulation licensing in a network environment it can be important to grab the correct level of licensing. Starting in SOLIDWORKS 2020, the level of simulation licensing can be selected either when enabling the add-in, or while the add-in is loaded. When going to the Add-Ins command manager bar, the button to enable SOLIDWORKS Simulation now has a down arrow to open a drop-down menu. In the drop-down menu, a specific license can be chosen e.g. […]

SOLIDWORKS 2020 What’s New – Free Body Forces for Nonlinear Studies

EmailFacebookLinkedInTwitterShare

A neat new feature that has been added to SOLIDWORKS 2020 is the ability to interrogate free body forces after running a nonlinear static or nonlinear dynamic study. The ability to compute and interrogate free body forces in SOLIDWORKS as part of simulation post-processing has existed for a long time but has been limited in previous versions of the software to linear static or dynamic studies. The first step in the process is to make sure the button for Compute […]
