### How to Optimize the Spacing of Electromagnetic Coils

##### Walter Frei April 20, 2017

Did you know that you can maximize the magnetic field strength of your electromagnetic coil designs by optimizing the spacing between the coils?

### 3 Ways to Optimize the Current in Electromagnetic Coils

##### Walter Frei April 10, 2017

We give you 3 ways to optimize the current in electromagnetic coil designs using the AC/DC Module and Optimization Module, add-on products to COMSOL Multiphysics®.

### How to Use Topology Optimization Results as Model Geometries

##### Hanna Gothäll February 1, 2017

Oftentimes, topology optimization is not the last step in your design process. In fact, you can use the results from a topology optimization study as model geometries for your next analysis.

### How to Use Acoustic Topology Optimization in Your Simulation Studies

##### GuestRené Christensen November 3, 2016

Today, guest blogger René Christensen of GN Hearing discusses the importance of acoustic topology optimization and how to apply it in COMSOL Multiphysics. Topology optimization is a powerful tool that enables engineers to find optimal solutions to problems related to their applications. Here, we’ll take a closer look at topology optimization as it relates to acoustics and how we optimally distribute acoustic media to obtain a desired response. Several examples will further illustrate the potential of this optimization technique.

### Improving Vascular Access for the Treatment of ESRD Patients

##### Bridget Cunningham March 1, 2016

When diagnosed with end-stage renal disease (ESRD), a form of permanent kidney failure, patients must undergo dialysis to replace the blood cleaning function of kidneys. Dialysis requires vascular access, a process where blood is removed, purified, and returned to the patient’s vasculature. Current methods for providing access, however, suffer from high failure rates. Combining CFD simulations with shape optimization techniques provides a way to better understand and predict such failure.

### Designing New Structures with Shape Optimization

##### Walter Frei December 29, 2015

While designing a structure, have you ever been unsure of how to achieve the best shape? If so, then you will want to add a useful technique called shape optimization to your COMSOL Multiphysics modeling skill set. Today, we will discuss the concept of shape optimization and demonstrate its use through a classical problem.

### Changing the Dimensions of a Model Using Shape Optimization

##### Walter Frei December 24, 2015

In this blog post, we will introduce the concept of shape optimization for adjusting part dimensions by using analytic sensitivity methods. If you have a single objective function that you want to improve, a set of geometric parameters that you want to change, as well as a set of constraints, then you can use the functionality of the Optimization Module and the Deformed Geometry interface in COMSOL Multiphysics to find the optimal structure without any remeshing. Let’s find out how!

3D printing, also known as additive manufacturing, has been a popular topic of discussion on the COMSOL Blog and throughout the scientific community. New initiatives have furthered the capabilities of this technology, while extending its reach in various fields of research, manufacturing, and design. With the help of COMSOL Multiphysics, researchers at the Netherlands Organization for Applied Scientific Research (TNO) are investigating the promise of 3D printing in the realm of material design.

### Finding a Structure’s Best Design with Topology Optimization

##### Benjamin Loubet September 23, 2015

Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.

### Multistudy Structural Optimization of a Bracket

##### Caty Fairclough September 11, 2015

Weight reduction is a key design focus in many applications. This is particularly true in the automotive industry, where lightweight materials help foster the development of fuel efficient cars. Maintaining the structural integrity of these materials is, of course, an important concern. As we will show you today, simulation is a valuable tool for addressing this challenge.
