Buckling is a common failure mode for slender structural components. This model shows how the buckling load of a diagonal brace can be maximized, while constraining the volume of the brace. Read More
The model shows how to estimate the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement. Typical numerical values of these quantities differ with around 10 orders of magnitude. Using a maximum likelihood strategy ... Read More
Electrode balancing is an important factor in the design of lithium-ion batteries. In this model, use the experimental open-circuit voltage of a cell and some basic assumptions, followed by an optimization solver, to find a proper electrode balancing. Get more details in this ... Read More
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This example simulates splitting properties using a simplified 2D geometry. The geometry is optimized using shape optimization in order to get the ... Read More
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using topology optimization with milling constraints. Read More
The model features the optimization of the geometry of a complex-shaped coil similar to those for induction heating applications. The geometry if fully built and parametrized in COMSOL Multiphysics (taking advantage of Geometry Parts; geometrical construction requires Design Module). The ... Read More
Topology optimization can result in novel designs due the extreme design freedom associated with the method. Conventional manufacturing techniques impose constraints on the geometry which are often violated by topology optimization. This model demonstrates how the milling constraint ... Read More
