In the Spotlight: Conserving and Restoring Art with Light

Bridget Cunningham March 10, 2015

Conserving and restoring art requires a balance between maintaining the quality of the work and respecting the artist’s initial creation. Advancing technologies now offer less invasive ways of analyzing artwork and bringing pieces back to their original condition. Since 2015 is the Year of Light, let’s explore how light can be used to conserve and restore paintings.

When using the COMSOL Multiphysics software to simulate wave electromagnetics problems in the frequency domain, there are several options for modeling boundaries through which a propagating electromagnetic wave will pass without reflection. Here, we will look at the Lumped Port boundary condition available in the RF Module and the Port boundary condition, which is available in both the RF Module and the Wave Optics Module.

Reciprocating engines are used extensively for power generation in a variety of applications, most notably within the automobile industry. In the design process, it is important to ensure that all of the engine’s parts can withstand high stresses and loads in order to maximize the operational lifetime. Here, we analyze fatigue in an engine’s connecting rods.

Today, we are pleased to introduce a new guest author, Vincent Bruyere of SIMTEC, who shares insight into the modeling of induction furnaces. Induction heating has become an important process in many applications, from cooking meals to manufacturing. It is valued for its precision and efficiency along with being a non-contact form of heating. In this guest post, I will describe how to build an induction furnace model in COMSOL Multiphysics and demonstrate how it can enhance your design.

In the diagnostics industry, developing devices that enable autonomous testing is an area of focus. One such device that has been available commercially for many years is the lateral flow test. With its easy-to-use format and short turn-around time for results, this device has become a valuable resource in medical diagnostics. See how researchers at the University of Rhode Island have built upon this technology to facilitate the diagnosis of more complex conditions.

Truck-mounted cranes are often used for load handling. In many cases, this involves carrying heavy materials, which can exert large forces on various parts of the crane. See how simulation can help identify the impact of these forces and enhance the crane’s operation.

When inside a room — a conference room, concert hall, or even a car — everyone has an opinion of when the “acoustics” are good or bad. In room acoustics, we want to study this notion of sound quality in a quantitative way. In short, room acoustics is concerned with assessing the acoustics of enclosed spaces. The Acoustics Module of COMSOL Multiphysics has several tools to simulate the acoustics of rooms and other confined spaces. I will present those here.

Continuous stirred tank reactors (CSTRs), or ideal stirred tank reactors, are frequently used in the chemical and biochemical industries. This reactor type operates at steady state and because of its good mixing properties, it is assumed that the composition throughout the reactor is uniform. Using a new model in the Reaction Engineering interface, we can visualize the dynamics within an ideal system of tank reactors.

We often get requests of the type “I would like to just enter my measured stress-strain curve directly into COMSOL Multiphysics”. In this new blog series, we will take a detailed look at how you can process and interpret material data from tests. We will also explain why it is not a good idea to just enter a simple stress-strain curve as input.
