This example shows how to use the Optimization Module to find a coil geometry giving a uniform magnetic field on axis and minimal field near the axis ends. Read More
This model performs a topological optimization for a Tesla microvalve. A Tesla microvalve inhibits backwards flow using friction forces rather than moving parts. The design can be optimized by distributing a specific amount of material within the modeling domain. The goal is to maximize ... Read More
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using parameter, shape and topology optimization. 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
In this parameter optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results ... Read More
The topology optimized Tesla microvalve is used as inspiration for a parametrized geometry. The optimization of this geometry takes erosion and dilation of the geometry into account by optimizing over a parametric sweep. In this example the optimization is driven by the worst of the 3 ... Read More
This model shows how to use the Free Shape Boundary feature to increase the stiffness of a wrench without increasing its mass. Read More
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Read More
The layout of a district heating network is designed using topology optimization. Read More
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution of porous material vary continuously. In this ... Read More
