How to Run on Clusters from the COMSOL Desktop® Environment

Lars Drögemüller March 9, 2018

Many types of analyses benefit from running the COMSOL Multiphysics® software on high-performance computing (HPC) hardware. This is one of the main reasons behind the Cluster Computing node, which helps seamlessly integrate the COMSOL® software with any kind of HPC infrastructure, while maintaining the convenience of a graphical user interface. In this blog post, learn how to run large simulations remotely on HPC hardware directly from the COMSOL Desktop® graphical environment.

Additive manufacturing has a wide array of applications, such as creating custom medical devices, aerospace components, and artwork. With the list of potential uses continuing to grow, it’s important that this type of manufacturing can keep up with the demand. However, analyzing and optimizing this complex process can be difficult. What can engineers do to overcome this challenge?

In 1801, the building around a glassmaker apprentice named Joseph von Fraunhofer collapsed, trapping him in rubble. While he didn’t know it at the time, this dramatic event (and resulting encounter with a prince-elector and politician) set him on the path toward improving the field of optics…

The foundation of a tunnel, dam, building, or other structure can be analyzed with a method called triaxial testing. Performing triaxial tests before, during, and after construction helps to ensure that structures are safe and reliable. To better understand the mechanics of soil and improve a structure’s stability, you can model the loading and unloading curves for a triaxial testing apparatus and test the soil’s model parameters in the COMSOL Multiphysics® software.

Frances Spence was an American mathematician and one of the first computer programmers in history. She is best known for her work as a programmer of the first digital computer, Electronic Numerical Integrator and Computer (ENIAC). Although she helped program the computer during WWII, her contributions to computer programming have only recently been recognized.

Today, guest blogger René Christensen of GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices. Topology optimization helps engineers design applications in an optimized manner with respect to certain a priori objectives. Mainly used in structural mechanics, topology optimization is also used for thermal, electromagnetics, and acoustics applications. One physics that was missing from this list until last year is microacoustics. This blog post describes a new method for including thermoviscous losses for microacoustics topology optimization.

Due to their small size and efficiency, compact heat exchangers are used in many application areas, including HVAC, nuclear power, and electronics. To help increase heat transfer rates and reduce pressure drops in these devices, a large number of studies have been performed, exploring concepts such as incorporating a deforming wall into the design. Using the COMSOL Multiphysics® software, you can evaluate a dynamic wall heat exchanger design.

Due to their inherent versatility and wideband frequency response, spiral slot antennas have a variety of applications for different microwave frequency bands. For example, these antennas are used for wireless communication, sensing, positioning, and tracking. To optimize the design of spiral slot antennas, engineers can use electromagnetics analysis to accurately calculate characteristics such as S-parameters and far-field patterns.

When a car hits a pothole, the suspension system can take on major damage in a matter of seconds. Suspension systems must be able to adapt to myriad road conditions while supporting the wheels, seats, and body of the car. To study the performance of a vehicle suspension system, you can use multibody analyses and a simplified lumped model of a mechanical system.

“I collected the instruments of life around me, that I might infuse a spark of being into the lifeless thing that lay at my feet.” So begins the iconic scene in Frankenstein, which was first published in 1818. While Shelley infused a spark of life into science fiction, Alessandro Volta helped foster innovation in the field of electrochemistry through also trying to “spark life” into a lifeless thing — literally.
