Geometry Selection Tips for No Penetration Contact Set in SolidWorks Simulation

When creating No Penetration Contact Sets in SolidWorks Simulation, the selected geometrical entities can be used either as Source (Set 1, indicated by a blue colour) or Target (Set 2, indicated by a pink colour) for the defined contact set. When you define a contact between…

SOLIDWORKS Simulation Nonlinear Analysis – Stepping Options

One of the most daunting tasks in creating nonlinear simulations is the proper settings of the time stepping options. This article will look at some recommendations for adjusting the time stepping options. The Nonlinear Autostepping Option In general, the Automatic (autostepping) option is recommended. This…

What is the Singularity Elimination Factor?

Singularity Error

Often times, when running a nonlinear static analysis, we receive an error shown in the image below. One of the solutions presented is to change the singularity elimination factor (SEF). So what is this SEF and what does it do? The Singularity Elimination Factor (SEF)…

SOLIDWORKS Simulation Contact Pressure Plots in 2D Simplification

For the first time, in SOLIDWORKS Simulation 2014, you can view the contact pressure plots in linear and nonlinear 2D Simplification studies. Contact pressure is developed in areas where two bodies come into contact during the analysis and no penetration contact is defined. To enhance the…

SolidWorks Simulation 2014: Contact Visualization Plot

Have you ever wondered what contacts you have created when running a simulation and what contacts have you missed? Imagine a large assembly with hundreds of contacts. Wouldn’t it be nice if you could get a summary of the contacts you have created to avoid those error messages which say that your model is unstable or not properly restrained? SolidWorks Simulation 2014 does just that. With a contact visualization plot, you can view how bodies are connected in multibody parts and assemblies. Before you run the analysis, you can detect the areas of contact applied by the global contact settings and any local contact sets. To view this plot, Right-click Connections, click Contact Visualization Plot Select Components: Select either the assembly or components (two and…

SW Simulation – Angular Tilt of a Deformed Face

I have been asked a number of times if there is a way to measure the angular tilt of a face on a solid body after it has deformed under a load. Solid Elements have no rotational degrees of freedom. Therefore only translational displacements can be reported in SolidWorks Simulation Although there is no direct way to measure the angular displacement of an entity with Solid Elements in a SolidWorks Simulation, we can use the translational displacements to evaluate the tilt on a face with a little help from trigonometry. Watch the attached video to see how we this can be achieved.

SolidWorks Simulation Database Files Description

For SolidWorks Simulation Files, the results are contained in one file with the extension CWR. Other information like study properties, materials, restraints, loads, and contact conditions are saved, in the SolidWorks part or assembly document. Many files are created by the solver during an analysis. Some of them are temporary files automatically deleted when the analysis is complete, others are result files which are meant to be put together and saved in the CWR file before being deleted when the model is closed. In case of abrupt termination of the solver or of SolidWorks, the deletion of the files will not take place, leaving many unnecessary files behind. They can be deleted manually, as only the CWR file is required to access the mesh and results. SolidWorks…
