In October 2023, we held a farewell party for Pal Sumit Kumar, who was a specially appointed researcher in our laboratory. The farewell party was held with students and teachers from the same research group as Sumit.

    Sumit has been researching CFD-FEM in our laboratory for about 5 years. It seems that he will be active at a university in the Netherlands in the future. He was a kind person who could answer any questions I had in fluent Japanese, and was a reliable person for the students in my lab.

    I wish you all the best in your future endeavors.
