Multiscale analysis is a research area that involves studying systems or phenomena at multiple levels of scale, from the micro to the macroscopic level. This approach allows researchers to better understand complex systems by taking into account the interactions and relationships between different scales. Multiscale analysis is commonly used in fields such as physics, biology, and engineering to study phenomena that span multiple scales, such as the behavior of materials, biological systems, and environmental processes. By integrating information and data from different scales, researchers can gain a more comprehensive understanding of the system as a whole.
