Multistudy Optimization of a Bracket

In this shape 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 from ... Saiba Mais

Optimization of a Tesla Microvalve

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 ... Saiba Mais

Time-Dependent Optimization

This tutorial demonstrates how to compute the periodic steady-state solution of a nonlinear model problem using an optimization solver. The solver modifies the initial conditions at the beginning of a period to match the solution at the end of the period. The model solves much faster ... Saiba Mais

Topology Optimization and Verification of an Acoustic Mode in a 2D Room

This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the sealing of a 2D room, that minimizes the average sound pressure level in an objective ... Saiba Mais

Topology Optimization of a Loaded Knee Structure

Imagine that you are designing a light-weight mountain bike frame that should fit in a box of a certain size and should weigh no more than 8 kg. Given that you know the loads on the bike, you can achieve this by distributing the available material while making sure that the stiffness of ... Saiba Mais

Sub-Component Lumping in Acoustics Using the Impedance Boundary Condition

This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Saiba Mais

Exporting and Importing a Topology Optimized Hook

The model studies optimal material distribution in a hook, which is symmetric about the z plane and consists of a linear elastic material, structural steel. It is subjected to two distributed edge load cases: One at the tip of the hook and one along its lower inner curve. The geometry is ... Saiba Mais
