About
Nicolas Kielbasiewicz is a CNRS Research Engineer at the Wave Propagation, Mathematical Study and Simulation laboratory (POEMS, UMR 7231) within the Applied Mathematics Unit of ENSTA Paris, a constituent school of Institut Polytechnique de Paris. His work focuses on the development and maintenance of scientific computing software, particularly the XLiFE++ finite element library.
His research interests span multiple areas of computational mathematics and scientific computing:
- Finite Element Method (FEM) and Boundary Element Method (BEM)
- Mesh generation and transformation
- Gravitational dynamics and multiscale modeling
- High-performance scientific computing
- C++ programming for numerical simulations
- Development of computational mathematics software libraries
Kielbasiewicz's publication record demonstrates a consistent focus on computational methods and software development. His work centers around the XLiFE++ library, which represents the evolution of earlier computational codes like Melina and Montjoie. His publications show expertise in both theoretical aspects of numerical methods and practical software implementation, with applications spanning electromagnetism, gravitational dynamics, and general scientific computing.
As a CNRS Research Engineer, Kielbasiewicz contributes significantly to both research and teaching activities at ENSTA Paris. He participates in courses SIM201 and SIM202 on numerical programming in C++, as well as the AMS301 course in the Master's program in Analysis, Modeling and Simulation.
He is an active member of the POEMS laboratory, collaborating with researchers across institutions including the University of Rennes I and INRIA Bordeaux Sud-Ouest. His work bridges theoretical mathematics with practical software development, creating tools that enable advanced computational research across multiple scientific domains.
