When a Pure Torque Causes Bending: The Limitation of Automatic Meshing in SolidWorks Simulation and a Comparison with Ansys Mechanical

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

Understanding Nonlinear Analysis

I came across this SolidWorks white paper and found it excellently written. It gives a clear and practical introduction to nonlinear finite element analysis. It explains when a linear analysis is usually sufficient and when nonlinear effects, such as large deformation, material yielding, contact, or buckling, need to be considered. The examples are simple and … Continue reading Understanding Nonlinear Analysis

Free Surface in SolidWorks Flow Simulation: A Dam-Break Flow Problem

In this post, we are going to use the free surface option to solve for a dam-break problem. The body of water is initially contained in a region on the left side. Then the water is released suddenly and starts to flow into the empty regions of the tank. Water is free to spill from … Continue reading Free Surface in SolidWorks Flow Simulation: A Dam-Break Flow Problem

Rotating Reference Frames in SolidWorks Flow Simulation: A Ceiling Fan Example

A rotating reference frame is usually used when modelling the flow through a table fan, a blower fan, an impeller, or a ceiling fan as shown in Figure 1. SolidWorks Flow Simulation allows for the use of rotating reference frames within the computational domain. These rotating reference frames can be defined either globally or locally. … Continue reading Rotating Reference Frames in SolidWorks Flow Simulation: A Ceiling Fan Example

Conjugate Heat Transfer in SolidWorks Flow Simulation

Conjugate heat transfer is the combination of convection and conduction heat exchange. By default, SolidWorks Flow Simulation considers the heat transfer due to convection within a fluid, however, it does not consider conduction through solids. This option must be selected when defining the analysis type in the Wizard (see Figure 2). For example, in this … Continue reading Conjugate Heat Transfer in SolidWorks Flow Simulation
