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.

One thing we haven’t talked much about so far in the Hybrid Modeling blog series is what speedup we can expect when adding more resources to our computations. Today, we consider some theoretical investigations that explain the limitations in parallel computing. We will also show you how to use the COMSOL software’s Batch Sweeps option, which is a built-in, embarrassingly parallel functionality for improving performance when you reach these limits.

What do heated soap bubbles, wavy clouds, and Jupiter’s Great Red Spot have in common? Their formation depends on the dynamics of the shear layer existing between two parallel streams moving at different velocities. This unstable motion, called Kelvin-Helmholtz instability, is ubiquitous and plays an important role in the dynamics of climate, for example. Let’s take a closer look at the onset and evolution of this instability with the help of Computational Fluid Dynamics (CFD) analysis.

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®.

Using the Graphics window in COMSOL Multiphysics can be a little tricky if you’re not too familiar with what it can do. But once you know the shortcuts, controlling the camera and view angles to create good graphics becomes quite straightforward. I hope the techniques shown here will help you produce graphics to visualize and present your work more easily.

When modeling computationally taxing geometries, you can save time by using cyclic symmetry to cut down on memory usage. This can be more complex for rotationally than axially symmetric geometries. However, with the Structural Mechanics Module you can easily solve a single section of an impeller model and still get accurate results.
