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.

How to Assign Fluid Pressure in CFD Simulations

December 30, 2016

There are many ways to experimentally measure pressure in a fluid. When setting up a CFD model, it is important to use the correct definition of pressure for assigning boundary conditions and defining the material properties. Today, we’ll explain the difference between relative and absolute pressure, why the COMSOL Multiphysics® software solves CFD problems using relative pressure, and when to use each definition of pressure in your models.

Investigating Whale Behavior with an Innovative Tagging Device

December 29, 2016

When whales dive beneath the ocean’s surface, what do they do? To answer this question, wildlife researchers need to track these enormous creatures for long periods of time and across great distances. To help with this challenging task, there is a new long-lasting tracking device called the advanced dive behavior (ADB) tag. With this device, researchers can enhance their understanding of whales as well as investigate ocean conditions and the effects of climate change.

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.

Introduction to Modeling Natural Convection in COMSOL Multiphysics®

December 23, 2016

Natural convection is a phenomenon found in many science and engineering applications, such as electronics cooling, indoor climate systems, and environmental transport problems. The CFD and Heat Transfer modules in version 5.2a of the COMSOL Multiphysics® software include functionality that makes it easier to set up and solve natural convection problems. In this blog post, we give an overview of natural convection, the new functionality, and some of the difficulties that we may stumble upon when modeling natural convection.
