In SOLIDWORKS Simulation, the default mesh size is the value that is initially assigned to the Global Size field of the Standard Mesh, but also influences the maximum and minimum used in Curvature Based meshes. What factors decide the default mesh size?

 

The rattleback is a stone shrouded in ancient mystery. Why is it that this stone only spins one way? Does it have no regard for conservation of angular momentum? In this article, we first present a naïvely constructed rattleback. Then we improve its performance with SOLIDWORKS Motion optimization. 

In this article, we compare tetrahedron and hexahedron elements and show an example of why the latter can be important to implement into your FEA (Finite Element Analysis) studies. To compare the tetrahedron to the hexahedron element, I ran a simple impact test in a few different FEA tools. I scaled the mesh size so that it took approximately 1000 seconds to solve each study.

 

As Application Engineers, we often hear from customers who are confused about the mathematics their simulation is calculating. Apart from the myriad of ways to set up a simulation study in SOLIDWORKS Simulation, we are sometimes asked to consider what equations are being used. I often hear, "When comparing them to laboratory testing, empirical data, and hand calculations, I’m not able to confirm what we are simulating”. 

 

A hybrid method of computational fluid dynamics analysis was used to enhance the design of a medical device to improve its ability to maintain a stable microclimate around a patient, but also to reduce both the computational efforts and the time required to obtain these results.

This study was part of the Virtual Optimization Pasta production process (OPAV) research project, which resulted in a simulation model that could be used by industrial pasta manufacturers to help them improve the quality and production process of their pasta.

If you need to share SOLIDWORKS Simulation data that is either protected sensitive design information or with someone who can't open SOLIDWORKS files, there are a couple of different options for exporting Simulation study results to other file formats. This can also be very useful for those who don't have the option of sending the full SOLIDWORKS file with the study and results.  

 

Gauss points are the points within each SOLIDWORKS Simulation element where the actual analysis happens. These are the points where the stress and strain outputs of SOLIDWORKS Simulation are calculated. SOLIDWORKS Simulation users can see nodal and element value plots by right-clicking on the plot of his/her choice then clicking edit definition. In the Advancearand Options, you will see node value and element value options.

 

At some point, a SOLIDWORKS Simulation user comes across a study that will not solve because there is something wrong with the no penetration contact sets that they have set up. In this article, I cover some of the investigative troubleshooting methods to employ when you suspect one or more no penetration contact sets in the analysis setup is incorrect and something needs to be changed for the study to be solved.
