The IX International Conference on Particle-Based Methods (PARTICLES 2025) will be organised on 20-22 October 2025, in Barcelona, Spain. The eight previous conferences in this series were held in Barcelona on 25-27 November 2009 and 26-28 October 2011, in Stuttgart on 18-20 September 2013, in Barcelona on 28-30 September 2015, in Hannover on 26-28 September 2017, in Barcelona on 28-30 October 2019, in Hamburg on 4-6 October 2021, in Milano on 9-11 October 2023 .

The objectives of PARTICLES 2025 are to present and discuss the fundamental principles, the new trends and the cutting-edge features of state-of-the-art Particle Methods for solving problems in engineering and applied sciences.

Particle Methods refer to those numerical methodologies using the concept of particles either to carry the information of the deforming continuum, such as Material Point Method (MPM), Smoothed Particle Hydrodynamics (SPH), Moving Particle Simulation (MPS), Particle Finite Element Method (PFEM), and Lattice-Boltzmann Method (LBM) or to represent computationally real physical particles, like in the Discrete Element Method (DEM) and Molecular Dynamics (MD).

The conference is one of the Thematic Conferences of the European Community on Computational Methods in Applied Sciences (ECCOMAS) and a Special Interest Conference of the International Association for Computational Mechanics (IACM).
