Abstract
Computational simulations have become an indispensable tool for solving complex problems in
engineering and science. One of the new computational techniques are the meshless methods,
covering several application fields in engineering. In this paper the Smoothed Particle
Hydrodynamics (SPH) method and its implementation in the explicit finite element code LSDYNA
is discussed. Its application and efficiency is shown with two practical engineering
application examples. The first example describes the modeling of fuel sloshing in a reservoir,
where different formulations, using mesh-based and meshless methods, are compared and
evaluated according to experimental measurements. The second example describes the impact
analysis of a cellular structure, where the influence of viscous fluid pore filler flow has been
studied. The SPH method proved to become a reliable and efficient tool, especially for solving
large scale and advanced engineering problems.
