SOLIDWORKS Simulation: Reaction Moment Using Solid Element

EmailFacebookLinkedInTwitterShare

When running an FEA on an assembly or large part the first thing we normally do is reduce the complexity of the geometry so that the calculation times remain short. At times this would mean that we would get rid of the main structure and only calculate the reaction forces and moments on a subassembly or smaller region of a part. While doing this we may end up using tetrahedron elements, or solid elements, to mesh our geometry. Solid elements […]

SOLIDWORKS Simulation: Causes of Incremental Strain Error

EmailFacebookLinkedInTwitterShare

This problem comes in during the calculation of two consecutive time steps in a nonlinear analysis. If the material deforms drastically without some proportional stress increase, then the software will stop the calculation and throw up an error message. The message may read something along the lines of “Incremental plastic strain is too large”. The solution may not be straightforward as to turning on an option. When you’re working with metals or non-rubber like materials, you should dig into the model […]

SOLIDWORKS 2019 What’s New – Distributed Coupling for Remote Load and Mass – #SW2019

EmailFacebookLinkedInTwitterShare

SOLIDWORKS regularly strives to create a more accurate representations of real world features. This year the Remote Load feature got an update that will give you more control over how the translations and rotations are applied to the geometry. The resultant forces and moments are now distributed over all the nodes on the selected face/edges/vertices equally as they are applied at the referenced location. The user interface has also gotten a face lift. Now it’s easier to see and apply […]

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

EmailFacebookLinkedInTwitterShare

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?

EmailFacebookLinkedInTwitterShare

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?

EmailFacebookLinkedInTwitterShare

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

EmailFacebookLinkedInTwitterShare

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

EmailFacebookLinkedInTwitterShare

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?

EmailFacebookLinkedInTwitterShare

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.

EmailFacebookLinkedInTwitterShare

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 […]
