SOLIDWORKS 2019 What’s New – Simulation Customized Numerical Format – #SW2019

EmailFacebookGoogle+LinkedInTwitterShare

In a growing global business environment, we are forced to work across different standards of punctuation and unit systems. SOLIDWORKS Simulation 2019 now allows all end users to change the way they punctuate numbers. You have the option to use commas’ or decimals for separators. This is all done through the Microsoft Windows system options. Go to the control panel and select Region and Language. Under the Formats tab, select Additional Settings. Within the Customize Formats window you can change […]

How to display part level simulation results in SOLIDWORKS Simulation?

There will be a point when you have a cluttered assembly and viewing your SOLIDWORKS simulation results can be difficult. In the past I have resorted to hiding and showing certain parts just to get a good view of the stress or displacement results. This method can be tedious but effective. Let’s take a look at the process. In Figure 1 we have an assembly that has all its parts shown. Now if you want to show the stress results […]

What are Workflow Sensors in SOLIDWORKS Simulation?

EmailFacebookGoogle+LinkedInTwitterShare

Sensors in SOLIDWORKS Simulation provide information about your model or analysis. Within the selection of simulation sensors, there is a workflow sensor that works differently compared to the other ones. First off, when you create a stress, strain, displacement, etc. sensor, it captures that specific information and reports it. However, the workflow sensor outputs the probed data of the plot you are viewing. As for creating the sensor you simply select Simulation Data for the sensor type and Workflow Sensitive […]

SOLIDWORKS Simulation: Spring Connector Differences – Face vs Point Selection

EmailFacebookGoogle+LinkedInTwitterShare

In SOLIDWORKS Simulation, anyone who uses FEA (Finite Element Analysis) and needs to simulate a spring, we know that it takes a large displacement formulation and a sizable mesh to accurately demonstrate a springs effect on an assembly. For this purpose, we have a spring connector that simulates exactly that. Although your assembly is still going through a large displacement it may or may not be going through a structural non-linearity. Through your trials and simulations please make sure you […]

SOLIDWORKS Simulation – Running a Static Analysis Throws an “Abnormal pretension is detected” Error

EmailFacebookGoogle+LinkedInTwitterShare

While running a static analysis in SOLIDWORKS Simulation an error window pops up that says, “Abnormal bolt pretension is detected during the modifying pretension cycle. Would you like to stop the application and check the setting?” What does this error mean and how do I fix it? There are a few reasons why this message is shown during the calculation time. At least two possible causes of this error are due to the boundary conditions that are applied. For instance: […]

What can you get from a topology study in SOLIDWORKS 2018?

EmailFacebookGoogle+LinkedInTwitterShare

As an engineer you can understand that there can be a multitude of solutions when creating machined or casted metal parts. One of the most difficult part of engineering these parts would be to start with a shape that not only looks good but can also serve to provide the most rigidity and least weight. Topology studies can show you the best shape to start with! Let’s work with this single body bridge, that is simply supported. Before you we […]

How to choose the correct time step in an impact analysis.

EmailFacebookGoogle+LinkedInTwitterShare

How to choose the correct time step in an impact analysis. When doing an impact test, time is the biggest concern. More specifically, the time increment you choose to analyze with. If you choose a time increment too large your study may fail to analyze, or if you choose a time increment too small it may take a very long time to compute and the results file size will also be extremely large. There are three rules you should follow […]

Numerical Instabilities in a Dynamic Systems SOLIDWORKS Motion has the ability to capture real world dynamic motion. You just have to understand what limitations there are to certain inputs such as the force, spring, motor, etc. Let’s take the example of the spring connector from the motion manager toolbar. Here we have a two mass system that is connected by a spring. The spring is attached using the faces of each block, however all generated forces are applied at the […]

When to use 2D Simplification

EmailFacebookGoogle+LinkedInTwitterShare

When to use 2D Simplification The idea behind simplifying your geometry for the sake of Simulation is to speed up the calculation. By simplifying, you are making assumptions on your boundary conditions i.e. no out of plane strain/stress, axisymmetric conditions. Also you are restricted to 2D elements. Even with these restrictions, contact problems become much easier to solve. You are allowed to select any face or plane to section with. Let’s say we want to see the weight of the […]

SOLIDWORKS 2018 What’s New – Sensors for SOLIDWORKS Simulation Mass Properties – #SW2018 The power of using design studies has just gotten larger. If you are ever looking to find the “best” design iteration, then you should be using design studies to get you there. SOLIDWORKS 2018 has put more options into sensors so that you can optimize to a variable and collect more information about your designs. The mass properties sensor can now track variables such as volume, surface […]
