Characterizing the Flow and Choosing the Right Interface

Nancy Bannach | April 7, 2014

Fluid flow is involved in many engineering applications. In addition to typical CFD simulations, which replace experiments in wind tunnels, flow must also be considered in the cooling of electronic devices or in the chemical industry, where reacting species are transported by a fluid. COMSOL Multiphysics offers dedicated interfaces for various flow types. When should we use the Laminar Flow or Turbulent Flow interface?

Previously, you saw how to compute stiffness of linear elastic structures in 0D and 1D. Today, we will expand on that and show you how to model this in 2D and 3D. We will also show you an alternate method to compute stiffness.

From an installation point of view, the main difference between a COMSOL CPU-Locked Single User (CPU) and Floating Network License (FNL) is how they are installed and managed. However, the FNL not only offers every single benefit of a CPU license, but also enables several additional features while greatly enhancing your workflow, allowing COMSOL Multiphysics to scale with your company’s growth.

Modeling in COMSOL Multiphysics involves a lot of tasks, such as choosing the right physics, defining the geometry, and setting up boundary conditions and domain settings. Additionally, material properties have to be defined for the materials included in the model. Such material data may come from the Material Library, but it often has to be obtained experimentally or from literature and imported into COMSOL Multiphysics.

To keep up with today’s fast-paced development cycles, R&D engineers and scientists need efficient tools to provide answers quickly and free them from routine tasks. COMSOL Multiphysics® has built-in features like parametric sweeps to increase simulation productivity. In addition to graphical modeling, COMSOL offers an Application Programming Interface (API) that you can use to automate any repetitive modeling step. Here’s how to get started with the COMSOL API for use with Java®.

It is well-known that you can use the RF Module to compute the impedance of lossless transmission line structures, such as coaxial cables of uniform cross section. But did you know that you can also compute an effective impedance for waveguides with non-uniform cross section? Let’s find out how!

Today, we will introduce the concept of structural stiffness and find out how we can compute the stiffness of a linear elastic structure subjected only to mechanical loading. In particular, we will explore how it can be computed and interpreted in different modeling space dimensions (0D and 1D) and which factors affect the stiffness of a structure.

The Leaning Tower of Pisa is regarded as one of the most famous landmarks in the world, although geotechnical engineers probably view it more as a construction gaffe. To prevent such a leaning fate, it could be useful to run an analysis in order to predict possible subsidence due to poroelastic deformation.

In this first entry of our new Geothermal Energy series, we introduce the concept of modeling geothermal processes and the many physical phenomena involved. We also show you an example model of a borehole heat exchanger.

When working with both SolidWorks® and COMSOL Multiphysics® via LiveLink™ for SolidWorks®, you can choose to synchronize selections. Here’s why you should and how to do it.

Born 179 years ago today, Josef Stefan was a brilliant Austrian physicist who studied radiation. He is credited with empirically deriving the relationship between the radiant energy of a blackbody and its temperature, known as the Stefan-Boltzmann law.
