Using the Discontinuous Galerkin Method to Model Linear Ultrasound

January 26, 2017

You can easily model acoustically large problems, like linear ultrasound, with a predefined physics interface that uses a memory-efficient approach called the discontinuous Galerkin method.

Finding the Best Coal Arrangement for Even Heat in a Grill

January 25, 2017

Pizza on the grill? It’s actually quite delicious. Here, we use heat transfer modeling to determine how the grill’s coals should be arranged for even heating.

Sebastien Perrier of Echologics discusses a simulation application used to locate leaks in underground pipe networks in his keynote presentation at the COMSOL Conference 2016 Boston.

How to Model an Anechoic Coating

January 5, 2017

Modeling an anechoic coating involves finding the smallest unit cell, truncating the geometry, and analyzing the wave diffration. The COMSOL® software includes predefined interfaces to do so.

Perform Rotordynamic Analyses of a Reciprocating Engine’s Crankshaft

January 2, 2017

You can use the Rotordynamics Module, an add-on to COMSOL Multiphysics®, to analyze the design of a crankshaft for a reciprocating engine.

Simulation Delivers Reliable Results for Piezoresistive Pressure Sensors

December 26, 2016

Designing MEMS devices, such as piezoresistive pressure sensors, comes with challenges. For instance, accurately describing the operation of these devices requires the integration of various physics. With the COMSOL Multiphysics® software, you can easily couple multiphysics simulations in order to test a device’s performance and generate reliable results. Today, we’ll look at one example that showcases such capabilities.

Optimize 3D Printers by Modeling the Glass-Transition Temperature

December 22, 2016

In 3D printers, suboptimal cooling and cure rates can negatively affect the manufactured parts and components. By optimizing a 3D printer’s design, we can ensure the quality of the printed objects. One research group used simulation to analyze the cooling process and the resulting glass-transition temperature of the polymer in a 3D printer. Let’s look at how they modeled the extrusion of acrylonitrile butadiene styrene (ABS) from a 3D printer that uses fused-deposition modeling (FDM®).
