Multiscale Multiphysics Coupling on a Finite Element Platform

In recent years numerical simulations are becoming fundamental for the design of many engineering components. For this reason many multiphysical and multiscale problems are investigated by coupling different existent software created specifically for solving each single problem. However, because...

description In recent years numerical simulations are becoming fundamental for the design of many engineering components.
