Session 1: How-To build a Mesh for a Tube Structure in Automated FEM on the 3DEXPERIENCE Platform

In this first video, we are going to show automated meshing on a bicycle frame. At the moment, we have the design model, which is tubular for the majority of the frame. So we will use the midsurface technique and mesh the frame with shell elements. The rear axle mounts, as well as the battery pack, are going to be represented by solid elements.

Watch our video to learn more about automated meshing.

Session 2: How-To define Welds in Automated FEM on the 3DEXPERIENCE Platform

In the first video, we shell and tet meshed a bicycle frame with the Automated FEM and using rule-based meshing. With the midsurfacing of the tubes though, we still have disconnected meshes and gaps between the tubes. In the real bicycle the tubes would be connected by welds. In the second video, we will show that for the analysis model of this bicycle frame we will use line fasteners to model these welds. 

Watch our video to learn more about line fasteners.

Session 3: How-To perform a Modal Analysis in Automated FEM on the 3DEXPERIENCE Platform

In the previous videos, we have automatically meshed a bike frame assembly. We also automatically setup line fasteners to act as welds between the tubes. Offscreen connections for the pedals and the rear wheel have been added. In the last video, we will setup a modal analysis to complete the project.

Watch our video to learn more about the setup of a modal analysis and the post process of the results.
