SOLIDWORKS Task Scheduler for Simulation Runs

By now, must people know the benefit that the “Run All Studies” and “Run Specified Studies” that SOLIDWORKS Simulation provides. These functions are limited in that they only work for a single part/ assembly file with or without different configurations. However, what happens when there is more than one file with multiple studies that need to be solved overnight? To accomplish this, we can turn to the often underused SOLIDWORKS Task Scheduler. Task scheduler allows users to automate a multitude of repetitive tasks including importing/ exporting files, Updating files, printing, rendering, and of course, updating Simulations in SOLIDWORKS. In order to run SOLDIWORKS Simulation studies with the Task Scheduler, simply

SOLIDWORKS: Meshing Errors in SOLIDWORKS Plastics 2016

Meshing Errors in SOLIDWORKS Plastics 2016   When trying to mesh a runner system with the part in SOLIDWORKS 2016, you may end up getting errors that don’t give you a clue to what is wrong. For instance, take a look at this message: when sewing connector, it without any face error!! This message came up when I was creating a solid mesh. Not sure if the message is a direct translation from another language but it doesn’t give you any direction on what is causing it or even what to change.     I had to follow some logic in this situation. Seeing that the runner mesh was not

SOLIDWORKS: How the Shell Can I Manage My SOLDIWORKS Simulation Shell Elements?

How the Shell Can I Manage My SOLDIWORKS Simulation Shell Elements?   If you were enticed by the title of this blog, then you are probably already aware of what a shell is and why they are so valuable. For those who are not aware, they are, in this context, a 2D element used in SOLIDWORKS Simulation. I will not bore you with too many details about shell elements, but instead show you some nifty techniques to help you manage and create shells more efficiently. Shells are defined by manually inputting several properties each time a body is converted to a shell element from a solid element. Who would want

SOLIDWORKS: Nonlinear Material Models in SOLIDWORKS Simulation

Nonlinear Material Models in SOLIDWORKS Simulation   If you are using SOLIDWORKS Simulation Premium, you have access to the Nonlinear study type. One of the advantages of this study type over the Linear Static study is the ability to apply loads and boundary conditions that vary over time. Another is the access to multiple material models that represent nonlinear material behaviors:   Nonlinear Elastic Hyper-elastic Elasto-plastic Super Elastic Nitinol Linear Visco-elastic Creep   Let me give you a brief description of each.   Nonlinear Elastic Model   For those materials that don’t exhibit any linear behavior, e.g., a stress-strain relationship like the graph below, the nonlinear elastic material model is

SOLIDWORKS: Simulation Beam Elements with Non-Planar Bonds

Simulation Beam Elements with Non-Planar Bonds   Recently I came across an issue bonding beam elements to non-planar faces on a body meshed as solid. It seemed like good information to share. Below is a simplified model of the model that was being simulated using SOLIDWORKS Simulation:         The red shaft was being treated as a beam element and loaded axially. The bottom of the shaft was fixed and the outside ring of the green body or “ring” as I will refer to it is fixed as well. The two parts in the assembly are bonded where the outer face of the shaft meets the inner face

Thermal stress study frozen in time? There’s a design study for that!

Before we get started I would like to provide a little background. There is no study type called “thermal stress” in SOLIDWORKS simulation. Thermal stress is simply the stress induced by a temperature load instead of a force or pressure. To obtain this information one must first create a thermal study and then use the output, temperature, as the prescribed load in a static study. One could also apply additional force and/or pressure loads, but this is atypical because the goal, for most applications, is to isolate the stress caused by heating or cooling. There are two types of thermal studies, steady-state and transient, and the default is steady-state. Suppose

SOLIDWORKS: Difference Between Ambient Temperature & Bulk Temperature in Simulation

Difference Between Ambient Temperature & Bulk Temperature in SOLIDWORKS Simulation   When creating a transient Thermal study in SOLIDWORKS, you are asked to input two temp settings. One of which is in the Temperature feature, labeled as Initial Temperature. This setting is for the air around model.     The other setting exists in the Convection feature. You are asked to input in a Bulk Ambient Temperature. This setting sets the initial temp of the model.       Ketul Application Engineer Computer Aided Technology

SOLIDWORKS Motion: Rendering Your Results in Visualize Professional

Rendering Your Results in Visualize Professional   SOLIDWORKS continues to amaze me!  In 2017, SOLIDWORKS raised the bar with the ability to send animations created in SOLIDWORKS Standard and Professional into Visualize Professional.  This ability allows you to re-use animation work already done at the CAD level to create fully rendered movies of your products for sales and marketing purposes.  The integration doesn’t stop with the Professional package; SOLIDWORKS Premium Simulation Motion results will also import into Visualize, allowing you to take your widgets to the next level and create epic movies with ease!   To test this, I used a 12-sided die and set up gravity, contact, friction, and materials

SOLIDWORKS: Leveraging Configurations in Simulation Products

Leveraging Configurations in SOLIDWORKS Simulation Products   If you use any of the SOLIDWORKS products related to simulation, i.e., Simulation (Finite Element Analysis-FEA), Flow (Computational Fluid Dynamics-CFD) or Plastics (Injection Molding) and haven’t been taking advantage of configurations, then this information is for you!   The SOLIDWORKS configuration functionality allows for multiple “What-if?” design ideas managed in the same file, and the simulation products can take advantage of this great feature, giving you the ability to analyze each design separately for easy comparison of results. If you aren’t yet familiar with configurations, the following images of the configuration manager show three configurations of an assembly with multiple component suppression states:
