My attempt at implementing SPH method for elastic systems based on analytical Riemann problem solution for interparticle interfaces. This video demonstrates an early collision dynamics test. Color is approximation of pressure(stress tensor trace), vectors are particle velocities.


Detailed method description may be found in "Smoothed Particle Hydrodynamics Using Interparticle Contact Algorithms", Journal of Computational Physics by A.N.Parshikov and S.A.Medin
