When given the choice, we’d all prefer our loudspeakers to project perfect sound; having a phone conversation with someone who sounds like a robot caught in a windstorm is less than ideal. The quality of the sound is, naturally, dependent on how well the speaker is designed, and COMSOL Multiphysics is the perfect tool to simulate and optimize loudspeaker designs because of its easy-to-use multiphysics nature. For a loudspeaker analysis to be accurate, you must be able to simulate from signal to sound with all the linking steps in between that determine how what you want to hear is transferred into what you actually will hear from a particular loudspeaker. Each step in the process will be interrelated, so it’s important to use this integrated multiphysics approach to capture each of these complex relationships. In the video at the bottom of this blog post, I will show you how our software can be used to perform a loudspeaker analysis.

Looking for ways to cut down on the time and computer memory required to run your simulation? Does your model exhibit some form of symmetry — axial symmetry, lines or planes of symmetry, or antisymmetry for example? Or perhaps your model exhibits periodicity? If you answered yes to those questions, you’re in luck. You can model symmetry or periodicity in COMSOL Multiphysics easily by either using a 1D or 2D axisymmetric dimensional simulation or by incorporating boundary conditions that represent a symmetry or periodic condition.

I’m back on the blog with the latest installment in the Postprocessing and Visualization Videos series. The two-part video shown here covers “Basic Visualization”. Chapter 1 and 2 will give you an overview of COMSOL’s visualization tools so that you can optimize how you view your model, both while setting up your physics and while postprocessing. I explain two tricks in the video that I’d like to draw your attention to in particular.

As promised, I’m back to introduce to you the second tutorial video in the new postprocessing blog series. This video covers the basics of creating plots, including some useful ways you can tweak and customize your plots. For example, have you ever wanted to improve the resolution of a plot, add or modify titles and axis labels, standardize the color bars over multiple graphs in one plot group, modify a deformation plot’s scaling, or view multiple plots in the COMSOL GUI simultaneously? All of these features are explained demo-style in this video on Creating and Customizing Plots in COMSOL:

Are you getting the most out of your simulations? There’s a wealth of options for creating plots and animations and for computing and exporting data in COMSOL, odds are you will find some neat features here. We want to get you off to a good start, so I’ve begun a series of tutorial videos covering a wide variety of topics in postprocessing. This tutorial series is suited for new and experienced users alike. You will get to learn the basics while picking up new tips and tricks in COMSOL’s latest release at the same time. For example, did you know that you can now create a comprehensive report of your simulation as a Microsoft Word document?
