This model demonstrates the inflation of a rubber balloon with four different hyperelastic material models. The results are compared with the analytical solution for a thin-walled, spherical vessel. Controlling the inflation of hyperelastic balloons is important in clinical ... En savoir plus
Multiscale modeling is a challenging issue in modern simulation. This occurs when there are vastly different scales in the same model. For example, your cell phone is approximately 10 cm, yet it receives GPS information from satellites 20,000 km away. In these models we examine several ... En savoir plus
This example demonstrates how to use the Poroelasticity multiphysics coupling between the Solid Mechanics and Darcy's Law interfaces to model linear biphasic poroviscoelastic behavior of soft biological tissues. The implementation is verified using two numerical benchmarks from the ... En savoir plus
A tubular centrifuge is a type of centrifugal separation device that is often used for separation of very fine solid particles from a liquid. It can be run in both a continuous and batch type configurations. The device usually consists of a cylindrical rotating bowl with a large aspect ... En savoir plus
Trusses are structural members that can only sustain axial forces, but no bending or torsion. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This ... En savoir plus
This example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex ...

Powder compaction is a popular manufacturing process not only in powder metallurgy, but also in the pharmaceutical industry. The Capped Drucker–Prager model is commonly used for simulating the compaction processes of pharmaceutical powders, where the material properties depend on the ... En savoir plus
This is an example of a Fabry-Perot cavity, the simplest optical resonator structure. It is a classical problem in optics and photonics. Two methods are shown for computing the Q-factor. The losses in this model are purely via radiation away from the resonator. En savoir plus
A waveguide filter is designed using shape optimization. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. En savoir plus
When a linear guide is loaded above the manufacturer's specification limit, one concern is whether the contact loads will introduce fatigue spalling. In this system analysis, the entire guide has been analyzed and the mostly damaging contact load has been identified to occur on a rail ... En savoir plus
