Applying a pure torque to a circular shaft should produce torsional deformation without bending. However, a finite element model may show an unexpected bending component even when the geometry, loading direction, and boundary conditions appear correct. This article uses a simple circular shaft to demonstrate how an automatically generated mesh can introduce a small unbalanced … Continue reading When a Pure Torque Causes Bending: The Limitation of Automatic Meshing in SolidWorks Simulation and a Comparison with Ansys Mechanical

Examples of 3D Mapped Meshing
In the last post, some examples of 2D mapped meshing are given. Here we are going to look at some examples of 3D mapped meshing. Similar to 2D mapped meshing, the strategy is straightforward: divide the domain in such a way that all the subdomains meet certain requirements, specify the element size or the number … Continue reading Examples of 3D Mapped Meshing
Construction Simulation of a Prestressed Reinforced Concrete Bridge: Part 1-Geometry and Meshing
The geometry of the bridge is directly generated from keypoints to lines and from keypoints to volumes. When meshing the volume, VSWEEP is used to ensure that all concrete elements are hexahedrons. The element size is controlled using LESIZE command and NDIV in L command. Prestress rebar is modelled by LINK8 element. Reinforced concrete is … Continue reading Construction Simulation of a Prestressed Reinforced Concrete Bridge: Part 1-Geometry and Meshing
