Stress Analysis of a Pipe Fitting from a CAD File
This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D CAD geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL. A cutting plane is defined ... Mehr lesen
Modifying Imported CAD Geometry with the Deformed Geometry Interface
When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ... Mehr lesen
SmartUQ Engineering Analytics Light-Weighting Application with COMSOL FEA Bracket Example
For decades, light-weighting has been a major area of research and concern in the automotive and aerospace industries. Industry leaders are adopting new software tools and investing ever greater engineering resources in adapting and optimizing their designs to be as lightweight and ... Mehr lesen
Modeling the Forces in a Bicycle Rim
Bicycle wheels are laced tangentially if they are intended to be used with disc brakes, because a radial pattern gives rise to larger forces in the rim. Otherwise, these rim forces are largely independent of the braking force. Mehr lesen

Mechanical Precession for the Axle of a Bicycle Pedal
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Mehr lesen
Golf Ball Trajectory
This model is used in the blog post "Why Do Golf Balls Have Dimples?". The trajectory of a golf ball is compared to the trajectory of a smooth ball using the Events interface and a system of ODEs in a 0D component. Mehr lesen
Geometric Parameter Optimization of a Bracket
This tutorial minimizes the mass of a bracket that is synchronized from PTC® Creo® Parametric™ via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical ... Mehr lesen
Metal Hydride Hydrogen Tank During Charging Neu
Metal hydride tanks offer safe hydrogen storage, thanks to their low reactivity, and a relatively high hydrogen density. When developing metal hydride hydrogen tank designs, modeling and simulation is useful for optimizing operating conditions, such as gas composition, pressure, and ... Mehr lesen
Hydrogen Storage in a Geological Formation Neu
Modeling and simulation is useful for evaluating the feasibility of storing hydrogen underground. In this example of a geological formation, hydrogen is injected through an injection well at a rate of 1 kg/s over a period of 2 years, until it is ready to be extracted and discharged ... Mehr lesen
