Multiscale modeling is a research area that involves studying systems or phenomena at multiple levels of scale, from the atomic and molecular level to the macroscopic or global level. This approach allows researchers to gain a more comprehensive understanding of complex systems by integrating information and interactions across different scales. Multiscale modeling is applied in various fields such as physics, chemistry, biology, materials science, and engineering. It enables scientists to simulate and predict the behavior of systems with a high level of accuracy and detail, by considering the interactions and dynamics at each level of scale. Overall, multiscale modeling provides a powerful tool for studying complex systems and processes, leading to advancements in scientific knowledge, technology development, and problem-solving in a wide range of disciplines.
