Singularities in Finite Element Models: Dealing with Red Spots
Seeing red? Explore common causes of singularities in your finite element models, as well as when and how to remove them and how to interpret your simulation results.
Using a Simulation App to Evaluate Fatigue Life in a Frame
The Frame Fatigue Life demo app is an example of how simulation apps can save you time and energy in evaluating the impact of fatigue on a structure. Take a look here >>
App: Improving the Payload Capacity of a Truck-Mounted Crane
Manufacturers and engineers looking to optimize the payload, or carrying, capacity of a truck-mounted crane can easily test parameters with a simulation app. Take a look at our demo app example.
Direct FSI Approach to Computing the Acoustic Radiation Force
In a follow-up to a previous blog post, we demonstrate a direct fluid–structure interaction approach for computing the acoustic radiation force in COMSOL Multiphysics®.
Modeling a Stacked Piezoelectric Actuator in a Valve
Piezoelectric valves are energy efficient, durable, and fast. You can model a key component of this device responsible for opening and closing the valve: a stacked piezoelectric actuator.
Part 2: Obtaining Material Data for Structural Mechanics from Measurements
Learn how to use nonlinear elastic and elastoplastic materials, as well as a method for using your measured data directly in COMSOL Multiphysics®. Part 2 of a series on hyperelastic materials.
Phase Decomposition Analysis of Loudspeaker Vibrations
A guest blogger from Dynaudio A/S discusses using COMSOL Multiphysics® to perform a phase decomposition analysis of the vibrations in a loudspeaker.
How Can I Build an Efficient Stirling Heat Pump?
Did you know that heat pumps are also called Stirling engines? These systems can operate on incredibly low temperature differences — some only need human body heat to work!
