The finite element method (FEM) is essentially very complex math used by engineers to reduce the number of prototypes and virtual experiments necessary to create a successful design. In previous posts, we discussed the advantages of the finite element method (FEM) and finite element analysis (FEA). Together, FEM and FEA are used to predict the structural behavior and integrity of a design.
Specialized finite element analysis software emerged in the 1970s. Now, it is common to find virtual testing integrated into the product development cycle. The global simulation software market size reached US$11.08 billion in 2020. It’s expected to grow 17.5% by 2028 while the specific FEA software market is anticipated to grow nearly 9% over the same period.
Key factors to support this expected market revenue growth across several industries include the increasing need to reduce manufacturing costs, as well as the need to investigate critical situations without actual risks. Simulation software for problem solving and decision making will be important at almost every stage of manufacturing, including product design, testing, and market launch, to mitigate potential challenges and boost financial returns. These are just a few of the ways that various industries utilize FEM and FEA.
Manufacturing Industry
The manufacturing industry is facing problems due to a significant increase in manufacturing costs, rapid demand fluctuations, and excessive equipment investment. Consequently, the industry is faced with the challenge of simultaneously achieving eco-friendly, high-quality, and low-cost products. To meet these demands, organizations are making an effort to improve the efficiency of the manufacturing process using FEM to predict various variables such as die alignment, material size deviation, and working temperature.
Energy Industry
Currently, rethinking energy transport is essential due to its broader applications for different energy systems. The study of heat and mass transportation has received remarkable consideration by physicists, engineers, and mathematicians. Researchers are looking at how to boost thermal transportation by mixing the nanoparticles in the base fluid mixture. Utilizing FEA, they are working to find numerical and graphical outcomes related to velocity and temperature versus various parameters. The present developments are applicable in automobile coolants, as well as the dynamics in fuel and the production of solar energy.
Rail Industry
In designing for passenger rail vehicle safety, one of the most challenging tasks for design engineers in the rail industry is predicting material durability. Numerical simulation is a convenient solution for prediction challenges, but a model’s predictions strongly depend on the availability—and accuracy—of material and assembly data. Advanced adhesive properties can provide designers with a robust data package to address modeling challenges through complex calculation methods or FEA. For multiple passenger rail interior and exterior applications, 3M has characterized three of its structural adhesive technologies to meet data requirements for two safety classes.
Commercial FEA Software
Ansys Mechanical recently became one of the first commercial finite element analysis (FEA) programs supporting AMD Instinct™ accelerators, which are the newest data center graphics processing units (GPUs). The accelerators are designed to provide exceptional performance for data centers and supercomputers to help solve the world’s most complex problems.
“Today’s large, complex engineering challenges require quick, predictively accurate simulations that scale,” said Brad McCredie, corporate vice president at AMD. The collaboration between Ansys and AMD will enable a notable speed boost for applications, which will allow researchers to run complex structural simulations in order to drive higher quality, more efficient designs for cars, planes, and a range of other products.

The global water crisis is causing problems worldwide. The United Nations estimates that 2.1 billion people do not have access to safe drinking water in their homes. This is relevant because those with access to clean water have a higher chance of leaving poverty, resisting disease, and seeking an education. The water crisis has severe implications that can limit health and economic prosperity.
Furthermore, scientists predict that droughts will become more frequent and severe in the upcoming century in the face of climate change. Increased droughts could spark violent conflicts in water-stressed regions. Fortunately, researchers are working toward solutions that will provide clean drinking water to even the most remote corners of the globe.
Potable Water from Salt Water
Desalination technologies are quickly becoming a necessity in at-risk areas. The most widely used desalination processes use reverse osmosis. Although reverse osmosis is energy efficient, it doesn’t work strongly on water with very high saline contents. Other desalination processes use external heat sources. However, these are not always readily available.
To make desalination viable for widespread use, the technology must become more energy-efficient and less costly. At the same time, it must not require chemicals that could detrimentally affect the environment or human health.
Researchers from a multi-institutional engineering research center based at Rice University called NEWT, Nanotechnology-Enabled Water Treatment, have a solution. They are developing a system that can be utilized in remote and domestic environments. Known as nanophotonics-enabled solar membrane distillation (NESMD), this system works with solar energy and nanoparticles to make saltwater drinkable.
“The integration of photothermal heating capabilities within a water purification membrane for direct, solar-driven desalination opens new opportunities in water purification,” says Menachem Elimelech, NEWT’s lead researcher for membrane processes.
The NESMD system uses a heat source is the membrane itself. Nanoparticles embedded on one side use sunlight to heat the water and operate the desalination process.
“Instead of heating the water before it comes into the module, you heat it on the membrane surface itself. One of the big advantages is that it can be used anywhere because it’s dependent on sunlight,” explains Akshay Deshmukh, a Ph.D. student in Elimelech’s lab at Yale.
This technology is still in its early stages. Potential uses include treating water from fracking and gas extraction operations as well as household water in less developed areas.
Starch and Solar
NEWT is not the only research center exploring water-related applications of solar power. In China, researchers at Dalian University of Technology are looking at another form of solar technology to produce drinking water. The research team is implementing the use of carbon nanosheets made from starch. This material is abundant, inexpensive, renewable, and doesn’t require hazardous materials.
These carbon nanosheets connect the desalination process to solar energy. The nanosheets are fashioned into electrodes for a capacitive deionization (CDI) system, which combines the desalination process with energy storage for maximum energy efficiency. While CDI is not a new field, this research has resulted in improved energy efficiency, cost savings, and safety.
The CDI desalination process occurs in two phases. The first phase consumes energy while the second phase generates energy. Because the energy can be stored and can actually be used to partially power the first phase, it results in huge efficiency gains. Pairing CDI systems with solar panels could facilitate their implementation in areas without electric grids while reducing fuel costs and greenhouse gas emissions.
The system must be refined before being brought to market. However, it’s a promising step toward bringing clean water to vulnerable communities worldwide. Furthermore, the researchers’ holistic approach illustrates the importance of considering energy efficiency, convenience, and safety when designing new technologies.
Drinking Water from Air
Startup Zero Mass Water makes solar panels that use the air to make drinkable water. The panel arrays, known as Source, collect water vapor from sunlight. It is then sterilized, converted into a liquid, and saved in a reservoir.
Source is available in eighteen different countries, from an orphanage in Lebanon to estates in California. Each solar panel is about $2,500 including installation. The panel delivers about two-five liters of water daily, equivalent to ten water bottles.
Zero Mass Water delivers its product to at-risk communities through its relationship with developers, local governments, and nonprofits.
Cody Friesen, a material scientist and CEO at Zero Mass Water, is a former engineering and materials science teacher at Arizona State University. He feels the company is a solution for the world’s water crisis, including poverty-stricken regions such as Morocco, Egypt, and India.
According to Friesen, “Today it takes far less energy (effectively none, since it’s entirely solar-powered) to create drinking water with Source than any other mechanism.”
