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

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.

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

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

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 – Sensor for Simulation Mass Properties – #SW2018

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 […]

SOLIDWORKS 2018 What’s New – Create Results Plots from Imported Data – #SW2018

SOLIDWORKS 2018 What’s New – Create Results Plots from Imported Data – #SW2018 This new functionality in SOLIDWORKS 2018 has a very small industrial niche. From time to time you can get featureless files that have to run an analysis.. If you have done setup and calculated previous projects that are the same in design, then you can export that data and apply it to the new file set. This can be especially helpful when the process takes a long […]

SOLIDWORKS 2018 What’s New – Displacement Control for Nonlinear Contacts – #SW2018

SOLIDWORKS 2018 What’s New – Displacement Control for Nonlinear Contacts– #SW2018 For those of you that have a need to do a buckling analysis, will remember the 2017 release allows you to conduct a buckling analysis on assemblies with no penetration contact conditions using the Arc Length control method. This opened up a whole new world what you can analyze for instance this guard rail: SOLIDWORKS 2018 has went a bit further on this functionality to allow users to use […]

What temp is assumed when no temp is applied in SOLIDWORKS Simulation?

For those of you who do thermal analysis on your designs, it’s important to know the behavior to avoid an incorrect boundary condition. This can be said for every analysis you conduct but this time I’m speaking of the default temperature. When performing a transient thermal study SOLIDWORKS SIMULATION asks that you apply an initial temp so that it knows which direction the energy is flowing. Most of us, including myself, are used to selecting faces when applying a load […]

SOLIDWORKS: Blended Curvature Based Mesh in SOLIDWORKS Simulation

Blended Curvature Based Mesh in SOLIDWORKS Simulation   Meshing a part appropriately might be tenuous at times, but it is certainly a lot easier in SOLIDWORKS than just about any other software. We don’t want to set the expectation that meshing is a problem for SOLIDWORKS. Getting a good aspect ratio around the smaller geometry can drive you and your computer a bit crazy, especially if you don’t know the smallest size of your geometry. SOLIDWORKS introduced the blended curvature based […]

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 […]
