The simulation of problems involving complex topological changes, requires the use of advanced techniques in order to allow tracking correctly the changes in the geometry. The use of Lagrangian particle methods, such as the PFEM allows a natural coupling with existing FE approaches and as such provides a very natural way for dealing with problems that can not be treated in other ways. Interestingly both surface coupled problems and volumecoupled problems can be treated by combining state of the art FE with the PFEM.
