A Discrete/Continuous Numerical Approach to Multi-physics

IFAC-PapersOnLine, 2015
Abstract A variety of technical applications are not only the physics of a single domain, but include several physical phenomena, and therefore are referred to as multi-physics. As long as the phenomena being taken into account is either continuous or discrete i.e. Euler or Lagrangian a homogeneous solution concept can be employed.
