How to Set Up a Mesh in COMSOL Multiphysics® for CFD Analyses

June 19, 2018

high tech bedrijven comsol 180619

The quality of a computational fluid dynamics (CFD) model is often determined by the quality of the mesh used to solve the problem. A good mesh facilitates convergence, reduces memory requirements, and results in accurate solutions. It is therefore worthwhile to invest time and thought into creating the mesh when solving a CFD problem. In this blog post, we describe the factors of a quality mesh and how to prepare a fluid flow model geometry for meshing.

What Is the Doppler Effect?

May 30, 2018

high tech bedrijven comsol 180530

The Doppler effect, or Doppler shift, occurs when the movement of an observer relative to a source (or vice versa) causes a change in wavelength or frequency. Discovered by Austrian physicist Christian Doppler in 1803, this phenomenon is experienced in many different ways, such as when an ambulance passes you by and you hear an audible change in pitch. Using the COMSOL Multiphysics® software, you can model the Doppler effect for acoustics applications.

Studying the Decoupling Effect of Electromagnetic Band Gap Structures

May 19, 2018

high tech bedrijven comsol 180519

Thanks to their ability to “tune out” specific frequencies, electromagnetic band gaps (EBGs) are found in many different applications. EBGs can suppress unwanted electromagnetic interference (EMI) and increase electromagnetic compatibility (EMC). These structures are commonly used between nearby antennas, which can help minimize undesirable coupling and thereby enhance their performance. However, using an EBG isn’t always a guarantee for better antenna isolation. To analyze the effectiveness of an EBG, engineers can use the COMSOL Multiphysics® software and add-on RF Module.

High-Fidelity Modeling of a Tunable Filter via Multiphysics Simulation

April 13, 2018

high tech bedrijven comsol 180413

Since high-speed communication is inevitable for evolving wireless systems, the demand for a higher data rate, higher frequency, larger spectrum, and wider bandwidth increases. When dealing with a wide bandwidth, multiple devices may have to be deployed in a wireless communication system to filter out unwanted noise and interfering signals, enhance the signal-to-noise ratio, and improve the sensitivity. A single tunable filter can replace these devices, reducing the system’s size and weight and the fabrication cost of multiple components.

Using the Algebraic Multigrid (AMG) Method for Large CFD Simulations

March 28, 2018

high tech bedrijven comsol 180328

The algebraic multigrid (AMG) solver provides robust solutions for large CFD simulations. Available as of version 5.3a of the COMSOL Multiphysics® software, the AMG method only requires one mesh, in contrast to the geometric multigrid (GMG) solver, which requires at least one extra coarser mesh. This eliminates the hassle associated with creating coarse meshes for complex geometries with small details that are difficult to mesh unless a fine mesh is used.

February 2, 2018

Complete en duidelijke informatie over de producten die uw organisatie maakt is essentieel om deze op de juiste manier te verkopen, troubleshooten, ontwerpen, assembleren en gebruiken. Technische communicatie is echter zelden in sync met het ontwerpproces. Dat is financieel gezien schadelijker dan u misschien op het eerste ogenblik denkt:

1. Incomplete handleidingen zorgen voor onnodige stilstand van de machine;

2. Het maken van ondersteunend materiaal remt het ontwerpproces (en dus time-to-market);

3. Het handmatig verzamelen van technische data is tijdrovend en achterhaald.

We still have a lot to learn about these ancient creatures, including if they could move and how they fed. A research team sought answers to these questions by using CFD simulation to study an extinct organism from Earth’s early oceans: Parvancorina.

Why Should I Use Automatic Wall Treatment for My CFD Modeling?

June 27, 2017

high tech bedrijven comsol 170627

Wall-bounded turbulent flows display extreme gradient close to the walls. The most accurate way to treat these gradients is to resolve them using a low Reynolds number model, which is computationally expensive. Industrial applications use wall functions, which model the flow closest to the wall rather than resolving it. Wall functions are robust and efficient, but not particularly accurate. New automatic wall treatment functionality in the COMSOL® software combines the benefits of wall functions and the low Reynolds number model.
