OUR CEO INVITES YOU TO LEARN FOR FREE #######, Almost 25 years ago, I began my career with the long-term aspiration to help improve our education system. Since joining LinkedIn, that passion has only grown stronger. That's one of many reasons I'm excited to announce the Week of Learning. From October 24-30, you'll be able to access over 5,000 courses on LinkedIn Learning, and it's all completely free (no fine print, no catches, and no credit card required). If you're wondering why, look no further than our vision: To create economi...

By GSC SOLIDWORKS Flow Simulation offers some great tools for analyzing rotating region problems. There are a lot of capabilities within the tool but, often times, there isn’t a lot of information about these capabilities. This article is meant to be a comprehensive guide to everything related to rotating region problems within SOLIDWORKS Flow Simulation. This will include explaining the different types of rotating region problems as well as the best practices associated with each one of them. There are two main types of rotating regions in Flow Simulation; global and local rotating regions. Both of these types are available for all fluid types; Newtonian and Non-Newtonians fluids. Global Rotating Region The global rotating region assumes you have a model that is completely symmetric about the rotating axis and all the components within the computational domain are rotating at the speed of the rotating reference frame. Due to the fact this type...

Top Four Mistakes Made Interpreting Analysis Results By CAPINC October 10, 2016 The most important part of an analysis is the interpretation of results, also called post-processing. Too much focus is often put on problem setup and solution – load magnitudes and directions, mesh particulars, solver choices, material properties – but all that effort is totally worthless if you misinterpret the results! Here are the most common mistakes, still made by the best of us. The Singularity   The most common source of numerical error is still the most common source of interpretation errors. This is when the solver divides by zero, resulting in erroneously high stresses as it tries to solve for infinity. The most common singularity locations are at zero-radius corners (sharp corners), and zero-area loads/restraints/contacts (edges and vertices), and zero-displacement fixtures. The best defense is to always run your study a second time, with a different mesh size, and ...
