A Guide to Publishing and Licensing Simulation Applications

Mark Robins January 7, 2019

In a previous blog post, we explored whether U.S. copyright law protects scientific models. That post concluded that models, alone, are frequently incapable of reflecting the type of creative expression required to be eligible for protection but also noted that functionality added to models — as occurs when building applications — may well contain such creative expression. Here, we explore the tools that COMSOL offers to help users of the COMSOL Multiphysics® software to publish and protect their proprietary applications.

Engineers are given significant freedom in their pursuit for lightweight structural components in airplanes and space applications, so it makes sense to use methods that can exploit this freedom, making topology optimization a popular choice in the early design phase. This method often requires regularization and special interpolation functions to get meaningful designs, which can be a nuisance to both new and experienced users. To simplify the solution of topology optimization problems, the COMSOL® software contains a density topology feature.

Whether you refer to it on a daily basis or it brings up memories of a middle school chemistry class, the periodic table of elements is a household name. The United Nations has even named 2019 as the International Year of The Periodic Table of Chemical Elements. Today, we discuss the history of the periodic table of elements as well as why it is being celebrated for an entire year…

An air ambulance flies overhead, speeding toward a hospital with a life-saving treatment. This “treatment” isn’t a new medicine or machine but an organ on its way to a patient on a transplant list. To keep the organ at just the right temperature during transport, it’s placed inside a special container called a cold or isothermal box. By using simulation, you can analyze the design of these boxes, making sure that they’re reliable for their life-saving purpose.

Carrier dynamics plays an important role in the transient behavior and frequency response of semiconductor devices. Here, we use two tutorial models of PIN rectifiers in the Semiconductor Module, an add-on to the COMSOL Multiphysics® software, to demonstrate the simulation of dynamical effects.

Radioactive materials have a long half-life, so they must be stored safely — usually in steel drums. These drums are then stored in confinement systems, which are designed with safety in mind (so that they can resist, for instance, a fire event exceeding two hours). Sogin, the state-owned company responsible for the Italian nuclear sites decommissioning and radioactive waste management, evaluated the fire resistance of a confinement system overpack using the COMSOL Multiphysics® software.

Optimizing the food dehydration process can be tricky, but it is helpful and necessary for areas with food shortages. In his keynote presentation at the COMSOL Conference 2018 Lausanne, Thijs Defraeye of Empa discussed how his team uses multiscale modeling to understand the drying process for soft cellular foods. If you missed his talk, you can watch a video recording of the presentation and read a summary below.

Reports are valuable for documenting and showcasing results from your simulations. As of version 5.4, the COMSOL Multiphysics® software includes support for report templates, which you can use to create custom reports. In this blog post, we describe how to add report templates and show some examples of how they can be useful for creating reports with specific layouts and contents.

Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect echoes. Modeling these devices often requires transient analyses with time of flight as output. Let’s discuss how to use the COMSOL Multiphysics® software to model a piezoelectric device as both a transmitter and receiver.

When it comes to synchrotron light sources, brighter is better. By using bright beams in their accelerator, researchers at the Advanced Photon Source (APS) synchrotron facility can efficiently gather detailed data. In collaboration with APS engineers, Nicholas Goldring of RadiaSoft LLC creates and distributes simulation applications for designing vacuum chambers relevant to the APS. Below, find a video recording and summary of his keynote talk from the COMSOL Conference 2018 Boston.

Traps are omnipresent in practical semiconductor devices. When modeling these devices, the Trap-Assisted Surface Recombination boundary condition adds the effects of charging and carrier capturing/releasing by surface or interface traps. Here, we examine a tutorial model of a metal-oxide-silicon capacitor (MOSCAP) to demonstrate how to use the feature in the Semiconductor Module, an add-on product to the COMSOL Multiphysics® software.
