Meshing – What is Average Element Size
Posted by Wasim in autodesk, Book Exercises, FEA-Tutorial on June 28, 2011
In the next couple of weeks I will be uploading a series of posts on the topic of meshing a key attribute in obtaining accurate stress analysis results. In this first article I am going to start of with how Inventor Stress Analysis creates meshes using the average element size value within the Mesh settings [...]
What is the difference between remote force and force?
Posted by Wasim in Autodesk FEA Simulation, FEA-Tips on June 22, 2011
The difference between remote force and force is that it allows the ability to define the location of the force (and not predetermined by selecting the faces of geometry like the force command), as illustrated below Another key difference between remote force and force is that remote force also induces moment/torque as soon as remote point [...]
Inventor 2012 Stress and Frame Analysis book now available
Posted by Wasim in Autodesk FEA Simulation, Book Exercises, FEA, Frame Analysis on May 6, 2011
The latest version of the Inventor Analysis book is now available. The format of the book has slightly changed in that it is smaller in size and book is now dedicated to Analysis section of Inventor only. Part 2 of the book will cover dynamic simulation. The book is still in full colour and more [...]
Tips & Guidance on how to overcome Stress Singularities in Models
Posted by Wasim in autodesk, Autodesk FEA Simulation, FEA-Tips on March 22, 2011
Stress Singularities is a major concern when analyzing results as they considerably distort results. They are also a main cause for non-convergence of results. So the first question is -what is stress singularity? This can be best explained by the following example The above bracket has a localized high stress around the force applied on [...]
