Happy New Year from the Javelin Simulation Team

It has been an exciting year for SOLIDWORKS Simulation, and, as always, we’ve seen some incredible changes happen to the software. The biggest change in the last year has to be the release of a new package of simulation tools: Simulation Standard. This is a great…

Nonlinear Analysis – Stress / Strain Curves for Material Models

Non-linear Analysis Featured

Depending on the settings, nonlinear analysis may require the input of stress / strain curves. When that is the case, the curve should be entered using the correct definition/values for stress and strain. As a matter of fact, several definitions of stress exist: true stress,…

When to use Nonlinear Analysis?

A Linear Static analysis can be performed on a problem if the following assumptions are valid: The material is linear elastic, where the geometry will return to its original shape if the load is removed. Deformations are small in relation to the dimensions of the…

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)…
