Resumen:
This paper presents a state of the art in the Particle Finite Element Method, normally calledPFEM, its emphasis in the new ideas oriented to extend its application not only to solve fluid struc-ture interaction and multifluid problems, also bring new opportunities to shorten the gap betweenengineering design times and computational simulation times for general problems when Eulerianformulation were typically chosen.In order to reduce the long history of this method here the starting point begins with the refor-mulation of the method to solve academic and real problems in real time or at least in drasticallyreduced computational times.The main topics involved in this paper are around the stability and the accuracy of Lagrangianformulations against its Eulerian counterpart shown through several academic benchmarks and adeep analysis of the efficiency revealing that the original method needs some new features. Theformer brought out a new integration method called X-IVAS and the later has produced a newversion of the method called PFEM in fixed Mesh.Once the method had shown its good performance and how the new features impact on the finalefficiency the last developments had been done in extending the application of this new method inmultifluids and other complex fluid mechanics problems like turbulence and reactive flows.
