The world of computational electromagnetics mourns the loss of Madabushi Venkadamachari (MVK) Chari, a pioneering figure whose work fundamentally shaped the design and analysis of electric machines. Chari, an IEEE Life Fellow, passed away on December 3rd at the age of 97, leaving behind a legacy of innovation and mentorship. His groundbreaking development of the finite element method (FEM) for analyzing nonlinear electromagnetic fields remains a cornerstone of modern engineering.
The finite element method, as explained by Fictiv, provides approximate solutions to complex problems by dividing them into smaller, manageable elements. This technique, initially conceived as a mathematical tool, found its practical application through Chari’s vision and dedication.
From Turbogenerators to MRI Magnets: A Career at General Electric
For 25 years, Chari served as a pivotal engineer and technical leader at General Electric’s research facility in Niskayuna, New York. There, he initially applied his finite element method to analyze the intricate end regions of large turbogenerators, progressively expanding its capabilities to encompass quasi-2D and ultimately, three-dimensional analyses. This evolution was critical in optimizing the performance and efficiency of these massive power generation systems.
Chari didn’t work in isolation. He fostered a collaborative environment, building a team dedicated to developing and refining finite element analysis (FEA) tools. The applications of this team’s work were remarkably diverse, ranging from the design of compact electric motors to the creation of powerful MRI magnets, demonstrating the versatility of his foundational work. His leadership was instrumental in translating theoretical advancements into tangible engineering solutions.
His contributions were formally recognized in 1993 with the prestigious IEEE Nikola Tesla Award, honoring his “pioneering contributions to finite element computations of nonlinear electromagnetic fields for design and analysis of electric machinery.” This award stands as a testament to the profound impact of his research.
Bridging Academia and Industry: A Life Dedicated to Learning
Chari’s academic journey began at Imperial College London, where he earned a master’s degree in electrical engineering. It was there he encountered Peter P. Silvester, a visiting professor and a leading figure in the numerical analysis of electromagnetic fields. This meeting proved formative, leading Chari to pursue a doctoral degree under Silvester’s guidance at McGill University in Montreal.
While Silvester focused on applying FEM to waveguide problems, Chari directed his research towards the complexities of saturated magnetic fields. After completing his Ph.D. in 1970, he joined General Electric, seamlessly transitioning from academic research to industrial application. He rose through the ranks, eventually managing the company’s electromagnetics division before transitioning to Rensselaer Polytechnic Institute in 1995.
At RPI, Chari continued to share his expertise as a visiting research and adjunct professor, teaching graduate and undergraduate courses in electric power engineering. He was renowned for his ability to nurture young engineers, providing mentorship and guidance that launched numerous careers. He also collaborated with the Electric Power Research Institute and the U.S. Department of Energy, furthering research into electric machines and transformers.
His career culminated with a period at Magsoft Corp., beginning in 2008, where he applied his expertise to develop specialized software for the U.S. Navy until his retirement in 2016. This final chapter demonstrated his enduring commitment to applying his knowledge to real-world challenges.
A Legacy of Mentorship and Inspiration
Beyond his technical achievements, Chari was remembered by colleagues as a generous mentor and a supportive friend. He championed the careers of others, notably facilitating the elevation of one colleague to IEEE Fellow status and opening doors for another at General Electric. His dedication to fostering talent extended beyond the laboratory, reflecting a deep-seated belief in the power of human potential.
Chari’s commitment to others stemmed from a distinguished family background. His father, M.A. Ayyangar, was a prominent figure in India’s independence movement, a respected mathematician, and ultimately, the speaker of the Indian Parliament’s lower house under Prime Minister Nehru. His wife, Padma, was a dedicated physician practicing in New York.
The story of his name, often shared with fondness, reveals a glimpse into his cultural heritage. Born into a Tamil tradition where formal names were not always immediate, he was initially known by the affectionate “house name” Kannah. When the time came for school enrollment, a family elder bestowed upon him the lengthy name Madabushi Venkadamachari, a testament to the importance of tradition and auspicious beginnings. He later adopted the more concise Madabushi V.K. upon immigrating to North America.

Understanding the Finite Element Method (FEM)
The finite element method (FEM) is a powerful numerical technique used to solve complex engineering and mathematical physics problems. It’s particularly valuable when analytical solutions are difficult or impossible to obtain. The core principle involves discretizing a continuous domain – like a physical object or a system – into a finite number of smaller, simpler subdomains called “finite elements.” These elements are interconnected at specific points called “nodes.”
By applying appropriate mathematical equations to each element and then assembling them into a global system of equations, engineers can approximate the behavior of the entire system. This allows for the analysis of stress, strain, heat transfer, fluid flow, and, crucially, electromagnetic fields. The accuracy of the solution depends on the size and type of elements used, as well as the complexity of the mathematical model.
FEM has become an indispensable tool in numerous industries, enabling the design and optimization of everything from aircraft and automobiles to bridges and medical devices. Its versatility and accuracy continue to drive innovation across a wide range of engineering disciplines.
