WebMultiscale modeling or multiscale mathematics is the field of solving problems that have important features at multiple scales of time and/or space. Important problems include multiscale modeling of fluids, solids, polymers, proteins, nucleic acids as well as various physical and chemical phenomena (like adsorption, chemical reactions, diffusion). An … Web30 nov. 2024 · The term multiscale modelingis widely used to describe a hierarchy of simulation approaches to treating systems across different scales. For a given scale of interest, one picks a simulation method capable of simulating systems at the length and time scales of interest. A common way of viewing this approach is a multiscale diagram, below.
